1 Introduction
1.1 Description
The TI PCI1410A device is a high-performance PCI-to-PC Card controller that supports a single PC Card socket compliant with the PC Card Standard. The PCI1410A device provides features that make it the best choice for bridging between PCI and PC Cards in both notebook and desktop computers. The PC Card Standard retains the 16-bit PC Card specification defined in PCI Local Bus Specification and defines the new 32-bit PC Card, CardBus, as being capable of full 32-bit data transfers at 33 MHz. The PCI1410A device supports both 16-bit and CardBus PC Cards, powered at 5 V or 3.3 V, as required.
The PCI1410A device is compliant with the PCI Local Bus Specification, and its PCI interface can act as either a PCI master device or a PCI slave device. The PCI bus mastering is initiated during 16-bit PC Card DMA transfers or CardBus PC Card bridging transactions. The PCI1410A device also is compliant with the latest PCI Bus Power
Management Interface Specification and PCI Bus Power Management Interface Specification for PCI to CardBus Bridges.
All card signals are buffered internally to allow hot insertion and removal without external buffering. The PCI1410A device is register-compatible with the Intel 82365SL-DF and 82365SL ExCA controllers. The PCI1410A internal data-path logic allows the host to access 8-, 16-, and 32-bit cards using full 32-bit PCI cycles for maximum performance. Independent buffering and a pipeline architecture provide an unsurpassed performance level with sustained bursting. The PCI1410A device also can be programmed to accept fast-posted writes to improve system-bus utilization.
Multiple system-interrupt signaling options are provided, including: parallel PCI, parallel ISA, serialized ISA, and serialized PCI. Furthermore, general-purpose inputs and outputs are provided for the board designer to implement sideband functions. Many other features designed into the PCI1410A device, such as socket-activity light-emitting diode (LED) outputs, are discussed in detail throughout the design specification.
An advanced complementary metal-oxide semiconductor (CMOS) process achieves low system power consumption, while operating at PCI clock rates up to 33 MHz. Several low-power modes enable the host power management system to further reduce power consumption.

Table 2–9. PCI Address and Data Terminals
I/O DESCRIPTION
PCI address/data bus. These signals make up the multiplexed PCI address and data bus on the primary interface. During the address phase of a primary bus PCI cycle, AD31–AD0 contain a 32-bit
I/O
address or other destination information. During the data phase, AD31–AD0 contain data.
PCI bus commands and byte enables. These signals are multiplexed on the same PCI terminals. During the address phase of a primary bus PCI cycle, C/BE3 During the data phase, this 4-bit bus is used as byte enables. The byte enables determine which
I/O
byte paths of the full 32-bit data bus carry meaningful data. C/BE0 C/BE1
applies to byte 1 (AD15–AD8), C/BE2 applies to byte 2 (AD23–AD16), and C/BE3 applies
to byte 3 (AD31–AD24). PCI bus parity. In all PCI bus read and write cycles, the PCI1410A device calculates even parity
across the AD31–AD0 and C/BE3 device outputs this parity indicator with a one-PCLK delay. As a target during PCI cycles, the calculated parity is compared to the initiator parity indicator . A compare error results in the assertion of a parity error (PERR
).
C/BE0 buses. As an initiator during PCI cycles, the PCI1410A
C/BE0 define the bus command.

I/O DESCRIPTION
PCI device select. The PCI1410A device asserts DEVSEL to claim a PCI cycle as the target device. As a PCI initiator on the bus, the PCI1410A device monitors DEVSEL target responds before timeout occurs, the PCI1410A device terminates the cycle with an initiator abort.
PCI cycle frame. FRAME is driven by the initiator of a bus cycle. FRAME is asserted to indicate that a bus transaction is beginning, and data transfers continue while this signal is asserted. When FRAME is deasserted, the PCI bus transaction is in the final data phase.
PCI bus grant. GNT is driven by the PCI bus arbiter to grant the PCI1410A device access to the PCI bus after the current data transaction has completed. GNT depending on the PCI bus parking algorithm.
Initialization device select. IDSEL selects the PCI1410A device during configuration space accesses. IDSEL can be connected to one of the upper 24 PCI address lines on the PCI bus.
PCI initiator ready. IRDY indicates the PCI bus initiator’s ability to complete the current data phase of the transaction. A data phase is completed on a rising edge of PCLK, when both IRDY are asserted. Until IRDY and TRDY are both sampled asserted, wait states are inserted.
PCI parity error indicator. PERR is driven by a PCI device to indicate that calculated parity does not match P A R when PERR see Section 4.4).
PCI bus request. REQ is asserted by the PCI1410A device to request access to the PCI bus as an initiator.
PCI system error. SERR is an output that is pulsed from the PCI1410A device when enabled through bit 8 (SERR_EN) of the command register (PCI offset 04h, see Section 4.4) indicating a system error has occurred. The PCI1410A device need not be the target of the PCI cycle to assert this signal. When SERR
is enabled in the command register, this signal also pulses, indicating that an address parity
error has occurred on a CardBus interface. PCI cycle stop signal. STOP is driven by a PCI target to request the initiator to stop the current PCI
bus transaction. STOP do not support burst data transfers.
PCI target ready. TRDY indicates the primary bus targets ability to complete the current data phase of the transaction. A data phase is completed on a rising edge of PCLK, when both IRDY are asserted. Until both IRDY and TRDY are asserted, wait states are inserted.

I/O DESCRIPTION
CardBus clock. CCLK provides synchronous timing for all transactions on the CardBus interface. All signals except CRST CVS1 are sampled on the rising edge of CCLK, and all timing parameters are defined with the rising edge of this signal. CCLK operates at the PCI bus clock frequency, but it can be stopped in the low state or slowed down for power savings.
CardBus clock run. CCLKRUN is used by a CardBus PC Card to request an increase in the CCLK frequency, and by the PCI1410A device to indicate that the CCLK frequency is going to be decreased.
CardBus reset. CRST brings CardBus PC Card-specific registers, sequencers, and signals to a known state. When CRST high-impedance state, and the PCI1410A device drives these signals to a valid logic level. Assertion can be asynchronous to CCLK, but deassertion must be synchronous to CCLK.

I/O DESCRIPTION
CardBus audio. CAUDIO is a digital input signal from a PC Card to the system speaker. The PCI1410A device supports the binary audio mode and outputs a binary signal from the card to SPKROUT.
CardBus lock. CBLOCK is used to gain exclusive access to a target. CardBus detect 1 and CardBus detect 2. CCD1 and CCD2 are used in conjunction with CVS1
I
and CVS2 to identify card insertion and interrogate cards to determine the operating voltage and card type.
CardBus device select. The PCI1410A device asserts CDEVSEL to claim a CardBus cycle as the target device. As a CardBus initiator on the bus, the PCI1410A device monitors CDEVSEL until a target responds. If no target responds before timeout occurs, the PCI1410A device terminates the cycle with an initiator abort.
CardBus cycle frame. CFRAME is driven by the initiator of a CardBus bus cycle. CFRAME is asserted to indicate that a bus transaction is beginning, and data transfers continue while this signal is asserted. When CFRAME is deasserted, the CardBus bus transaction is in the final data phase.
CardBus bus grant. CGNT is driven by the PCI1410A device to grant a CardBus PC Card access to the CardBus bus after the current data transaction has been completed.
CardBus interrupt. CINT is asserted low by a CardBus PC Card to request interrupt servicing from the host.
CardBus initiator ready. CIRDY indicates the ability of the CardBus initiator to complete the current data phase of the transaction. A data phase is completed on a rising edge of CCLK when both CIRDY and CTRDY are asserted. Until both CIRDY and CTRDY are sampled asserted, wait states are inserted.
CardBus parity error. CPERR reports parity errors during CardBus transactions, except during special cycles. It is driven low by a target two clocks following that data when a parity error is detected.
CardBus request. CREQ indicates to the arbiter that the CardBus PC Card desires use of the CardBus bus as an initiator.
CardBus system error. CSERR reports address parity errors and other system errors that could lead to catastrophic results. CSERR device can report CSERR
CardBus stop. CSTOP is driven by a CardBus target to request the initiator to stop the current CardBus transaction. CSTOP target devices that do not support burst data transfers.
CardBus status change. CSTSCHG alerts the system to a change in the card status, and is used as a wake-up mechanism.
CardBus target ready . CTRDY indicates the ability of the CardBus target ability to complete the current data phase of the transaction. A data phase is completed on a rising edge of CCLK, when both CIRDY and CTRDY are asserted; until this time, wait states are inserted.

3.1 Power-Supply Sequencing
The PCI1410A device contains 3.3-V I/O buffers with 5-V tolerance, requiring a core power supply and clamp voltages. The core power supply always is 3.3 V. The clamp voltages can be either 3.3 V or 5 V, depending on the interface. The following power-up and power-down sequences are recommended.
The power-up sequence is:
1. Apply 3.3-V power to the core.
2. Assert GRST
to the device to disable the outputs during power up. Output drivers must be powered up in
the high-impedance state to prevent high current levels through the clamp diodes to the 5-V supply.
3. Apply the clamp voltage.
The power-down sequence is:
1. Use GRST
to switch outputs to a high-impedance state.
2. Remove the clamp voltage.
3. Remove the 3.3-V power from the core.

3.2 I/O Characteristics

3.3 Clamping Voltages
The clamping voltages are set to match whatever external environment the PCI1410A device is interfaced with: 3.3 V or 5 V. The I/O sites can be pulled through a clamping diode to a voltage rail that protects the core from external signals. The core power supply always is 3.3 V and is independent of the clamping voltages. For example, PCI signaling can be either 3.3 V or 5 V, and the PCI1410A device must reliably accommodate both voltage levels. This is accomplished by using a 3.3-V I/O buffer that is 5-V tolerant, with the applicable clamping voltage applied. If a system designer desires a 5-V PCI bus, V

3.4 Peripheral Component Interconnect (PCI) Interface
The PCI1410A device is fully compliant with the PCI Local Bus Specification. The PCI1410A device provides all required signals for PCI master or slave operation, and can operate in either a 5-V or 3.3-V signaling environment by connecting the V device provides the optional interrupt signal INTA
3.4.1 PCI Bus Lock (LOCK)
The bus-locking protocol defined in the PCI Local Bus Specification is not highly recommended, but is provided on the PCI1410A device as an additional compatibility feature. The PCI LOCK terminal via the multifunction routing register. See Section 4.30, Multifunction Routing Register, the use of LOCK

An agent may need to do an exclusive operation because a critical access to memory might be broken into several transactions, but the master wants exclusive rights to a region of memory. The granularity of the lock is defined by PCI to be 16 bytes, aligned. The LOCK without interfering with nonexclusive real-time data transfer, such as video.

The PCI1410A device supports all LOCK PCI-to-CardBus bridges. This includes disabling write posting while a locked operation is in progress, which can solve a potential deadlock when using devices such as PCI-to-PCI bridges. The potential deadlock can occur if a CardBus target supports delayed transactions and blocks access to the target until it completes a delayed read.

3.4.2 Loading Subsystem Identification
The subsystem vendor ID register (PCI offset 40h, see Section 4.26) and subsystem ID register (PCI offset 42h, see Section 4.27) make up a doubleword of PCI configuration space located at offset 40h for functions 0 and 1. This doubleword register is used for system and option card (mobile dock) identification purposes and is required by some operating systems.
The PCI1410A device offers two mechanisms to load a read-only value into the subsystem registers. The first mechanism relies upon the system BIOS providing the subsystem ID value. The default access mode to the subsystem registers is read-only, but can be made read/write by clearing bit 5 (SUBSYSRW) in the system control register (PCI offset 80h, see Section 4.29). When this bit is cleared, the BIOS can write a subsystem identification value into the registers at PCI offset 40h. The BIOS must set the SUBSYSRW bit such that the subsystem vendor ID register and subsystem ID register are limited to read-only access. This approach saves the added cost of implementing the serial electrically erasable programmable ROM (EEPROM).
In some conditions, such as in a docking environment, the subsystem vendor ID register and subsystem ID register must be loaded with a unique identifier via a serial EEPROM. The PCI1410A device loads the data from the serial EEPROM aft e r a r eset of the primary bus. Note that the SUSPEND core, including the serial bus state machine (see Section 3.8.4, Suspend Mode, for details on using SUSPEND
input gates the PCI reset from the entire PCI1410A

The PCI1410A device provides a two-line serial bus host controller that can interface to a serial EEPROM. See Section 3.6, Serial Bus Interface,
for details on the two-wire serial bus controller and applications.

3.5.1 PC Card Insertion/Removal and Recognition
The PC Card Standard addresses the card-detection and recognition process through an interrogation procedure that the socket must initiate on card insertion into a cold, nonpowered socket. Through this interrogation, card voltage requirements and interface (16-bit versus CardBus) are determined.
The scheme uses the card-detect and voltage-sense signals. The configuration of these four terminals identifies the card type and voltage requirements of the PC Card interface. The encoding scheme is defined in the PC Card Standard and in Table 3–1.

3.5.3 Zoomed-Video Support
The PCI1410A device allows for the implementation of ZV for PC Cards. ZV is supported by setting bit 6 (ZVENABLE) in the card control register (PCI offset 91h, see Section 4.32) on a per-socket function basis. Setting this bit puts PC Card 16 address lines ADDR25–ADDR4 of the PC Card interface in the high-impedance state. These lines can then transfer video and audio data directly to the appropriate controller. Card address lines ADDR3–ADDR0 can still access PC Card CIS registers for PC Card configuration. Figure 3–5 illustrates a PCI1410A ZV implementation.

Not shown in Figure 3–5 is the multiplexing scheme used to route a socket ZV source or an external ZV source to the graphics controller. A typical external source might be provided from a high-speed serial bus like IEEE 1394. The PCI1410A device provides ZVSTAT and ZVSEL0

3.5.4 Ultrazoomed Video
Ultrazoomed video is an enhancement to the PCI1410A DMA engine and is intended to improve the 16-bit bandwidth for MPEG I and MPEG II decoder PC Cards. This enhancement allows the PCI1410A device to fetch 32 bits of data from memory, versus the PCI11XX/PCI12XX 16-bit fetch capability. This enhancement allows a higher sustained throughput to the 16-bit PC Card because the PCI1410A device prefetches an extra 16 bits (32 bits total) during each PCI read transaction. If the PCI bus becomes busy, the PCI1410A device has an extra 16 bits of data to perform back-to-back 16-bit transactions to the PC Card before having to fetch more data. This feature is built into the DMA engine, and software is not required to enable this enhancement.
NOTE: The PCI11XX and PCI12XX series CardBus controllers have enough 16-bit bandwidth to support MPEG II PC Card decoders. But, it was decided to improve the bandwidth even more in the PCI14XX series CardBus controllers.
3.5.5 Internal Ring Oscillator
The internal ring oscillator provides an internal clock option for the PCI1410A device so that the PCI clock is not required for the PCI1410A device to power down a socket or interrogate a PC Card. This internal oscillator operates nominally at 16 kHz and can be enabled by setting bit 27 (P2CCLK) of the system control register (PCI offset 80h, see Section 4.29) to 1. This function is disabled by default.

3.5.6 Integrated Pullup Resistors for PC Card Interface
The PC Card Standard requires pullup resistors on various terminals to support both CardBus and 16-bit card configurations. Unlike the PCI1210 or PCI1211 device, which required external pullup resistors, the PCI1410A device has integrated all of these pullup resistors.

3.5.7 SPKROUT and CAUDPWM Usage
SPKROUT carries the digital audio signal from the PC Card to the system. When a 16-bit PC Card is configured for I/O mode, the BVD2 terminal becomes SPKR is referred to as CAUDIO. SPKR
passes a TTL-level digital audio signal to the PCI1410A device. The CardBus CAUDIO signal also can pass a single-amplitude binary waveform. The binary audio signal from the PC Card socket is used in the PCI1410A device to produce SPKROUT. This output is enabled by bit 1 (SPKROUTEN) in the card control register (PCI offset 91h, see Section 4.32).
. This terminal also is used in CardBus binary audio applications, and
Older controllers support CAUDIO in binary or PWM mode, but use the same terminal (SPKROUT). Some audio chips may not support both modes on one terminal and may have a separate terminal for binary and PWM. The PCI1410A implementation includes a signal for PWM, CAUDPWM, which can be routed to an MFUNC terminal. Bit 2 (AUD2MUX), located in the card control register, is programmed to route a CardBus CAUDIO PWM terminal to CAUDPWM. See Section 4.30, Multifunction Routing Register, for details on configuring the MFUNC terminals.
Figure 3–7 illustrates a sample application using SPKROUT and CAUDPWM.

3.5.8 LED Socket Activity Indicators
The socket activity LEDs indicate when a PC Card is being accessed. The LED_SKT signal can be routed to the multifunction terminals. When configured for LED output, this terminal outputs an active high signal to indicate socket activity. See Section 4.30, Multifunction Routing Register,
The LED signal is active high and is driven in pulses of 64-ms duration. When the LED is not being driven high, it is driven to a low state. Either of the two circuits shown in Figure 3–8 can be implemented to provide LED signaling, and it is left for the board designer to implement the circuit that best fits the application.
The LED activity signals are valid when a card is inserted, powered, and not in reset. For PC Card-16, the LED activity signal is pulsed when READY/IREQ or CREQ

As indicated, the LED signals are driven for a period of 64 ms by a counter circuit. To avoid the possibility of the LED appearing to be stuck when the PCI clock is stopped, the LED signaling is cut off when the SUSPEND
signal is
asserted, when the PCI clock is to be stopped during the clock run protocol, or when in the D2 or D1 power state. If any additional socket activity occurs during this counter cycle, the counter is reset and the LED signal remains
driven. If socket activity is frequent (at least once every 64 ms), the LED signal remains driven.
3.5.9 PC Card-16 Distributed DMA Support
The PCI1410A device supports a distributed DMA slave engine for 16-bit PC Card DMA support. The distributed DMA (DDMA) slave register set provides the programmability necessary for the slave DMA engine. Table 3–2 provides the DMA register configuration.
Two socket function-dependent PCI configuration header registers that are critical for DMA are the socket DMA register 0 (PCI offset 94h, see Section 4.35) and the socket DMA register 1 (PCI offset 98h, see Section 4.36).
3–8
Distributed DMA is enabled through socket DMA register 0, and the contents of this register configure the PC Card-16 terminal (SPKR
, IOIS16, or INPACK), which is used for the DMA request signal, DREQ. The base address of the DMA slave registers and the transfer size (bytes or words) are programmed through the socket DMA register 1. See the programming model and register descriptions in Section 7 for details.

The DMA registers contain control and status information consistent with the 8237 DMA controller; however, the register locations are reordered and expanded in some cases. While the DMA register definitions are identical to those of the same name in the 8237 DMA controller, some register bits defined in the 8237 DMA controller do not apply to distributed DMA in a PCI environment. In such cases, the PCI1410A device implements these obsolete register bits as read-only, nonfunctional bits. The reserved registers shown in Table 3–2 are implemented as read-only and return 0s when read. Write transactions to reserved registers have no effect.
The DMA transfer is prefaced by several configuration steps that are specific to the PC Card and must be completed after the PC Card is inserted and interrogated. These steps include setting the proper DREQ
signal assignment, setting the data transfer width, and mapping and enabling the DMA register set. As discussed above, this is done through socket DMA register 0 and socket DMA register 1. The DMA register set is then programmed similarly to an 8237 controller, and the PCI1410A device awaits a DREQ
assertion from the PC Card requesting a DMA transfer.
DMA writes transfer data from the PC Card-to-PCI memory addresses. The PCI1410A device accepts data 8 or 16 bits at a time, depending on the programmed data width, and then requests access to the PCI bus by asserting its REQ signal. Once the PCI bus is granted in an idle state, the PCI1410A device initiates a PCI memory write command to the current memory address and transfers the data in a single data phase. After terminating the PCI cycle, the PCI1410A device accepts the next byte(s) from the PC Card until the transfer count expires.
DMA reads transfer data from PCI memory addresses to the PC Card application. Upon the assertion of DREQ PCI1410A device asserts REQ
to acquire the PCI bus. Once the bus is granted in an idle state, the PCI1410A device
, the
initiates a PCI memory read operation to the current memory address and accepts 8 or 16 bits of data, depending on the programmed data width. After terminating the PCI cycle, the data is passed on to the PC Card. After terminating the PC Card cycle, the PCI1410A device requests access to the PCI bus again, until the transfer count has expired.
The PCI1410A target interface acts normally during this procedure and accepts I/O reads and writes to the DMA registers. While a DMA transfer is in progress and the host resets the DMA channel, the PCI1410A device asserts TC and ends the PC Card cycle(s). TC is indicated in the DMA status register (DMA offset 08h, see Section 7.5). At the PC Card interface, the PCI1410A device supports demand mode transfers. The PCI1410A device asserts DACK during the transfer unless DREQ operations and is mapped to the WE PC Card REG
signal in all transfers, and the DREQ terminal is routed to one of three options, which is programmed
is deasserted before TC. TC is mapped to the OE PC Card terminal for DMA write
PC Card terminal for DMA read operations. The DACK signal is mapped to the
through socket DMA register 0.

3.5.10 PC Card-16 PC/PCI DMA
DMA CHANNEL
Some chip sets provide a way for legacy I/O devices to do DMA transfers on the PCI bus. In the PC/PCI DMA protocol, the PCI1410A device acts as a PCI target device to certain DMA-related I/O addresses. The PCI1410A PCREQ PCGNT PCGNT Routing Register,
signals are provided as a point-to-point connection to a chipset supporting PC/PCI DMA. The PCREQ and signals may be routed to the MFUNC2 and MFUNC5 terminals, respectively . See Section 4.30, Multifunction
for details on configuring the multifunction terminals.
Under the PC/PCI protocol, a PCI DMA slave device (such as the PCI1410A device) requests a DMA transfer on a particular channel using a serialized protocol on PCREQ grants the channel through a serialized protocol on PCGNT
. The I/O DMA bus master arbitrates for the PCI bus and
when it is ready for the transfer. The I/O cycle and memory
cycles are then presented on the PCI bus, which performs the DMA transfers similarly to legacy DMA master devices. PC/PCI DMA is enabled for each PC Card-16 slot by setting bit 19 (CDREQEN) in the respective system control
register (PCI o ffset 80h, see Section 4.29). On power up, this bit is reset and the card PC/PCI DMA is disabled. Bit 3 (CDMA_EN) of the system control register is a global enable for PC/PCI DMA, and is set at power up and never cleared if the PC/PCI DMA mechanism is implemented. The desired DMA channel for each PC Card-16 slot must be configured through bits 18–16 (CDMACHAN field) in the system control register. The channels are configured as indicated in Table 3–3.

As in distributed DMA, the PC Card terminal mapped to DREQ must be configured through socket DMA register 0 (PCI offset 94h, see Section 4.35). The data transfer width is a function of channel number, and the DMA slave registers are not used. When a DREQ device decodes the I/O addresses listed in Table 3–4 and performs actions dependent upon the address.
When the PC/PCI DMA is used as a PC Card-16 DMA mechanism, it may not provide the performance levels of DMA; however, the design of a PCI target implementing PC/PCI DMA is considerably less complex. No bus master state machine is required to support PC/PCI DMA, since the DMA control is centralized in the chipset. This DMA scheme often is referred to as centralized DMA for this reason.

and SMBus components.
3.6.1 Serial Bus-Interface Implementation
To enable the serial interface, a pullup resistor must be implemented on the VCCD0 and VCCD1 terminals and the appropriate pullup resistors must be implemented on the SDA and SCL signals, that is, the MFUNC1 and MFUNC4 terminals. When the interface is detected, bit 3 (SBDETECT) in the serial bus control and status register (PCI offset B3h, see Section 4.50) is set. The SBDETECT bit is cleared by a writeback of 1.
The PCI1410A device implements a two-pin serial interface with one clock signal (SCL) and one data signal (SDA). When pullup resistors are provided on the VCCD0 terminal and the SDA signal is mapped to the MFUNC1 terminal. The PCI1410A device drives SCL at nearly 100 kHz during data transfers, which is the maximum specified frequency for standard-mode I be located at address A0h.

3.6.2 Serial Bus-Interface Protocol
The SCL and SDA signals are bidirectional, open-drain signals and require pullup resistors as shown in Figure 3–9. The PCI1410A device supports up to 100-Kb/s data transfer rate and is compatible with standard-mode I 7-bit addressing.

All data transfers are initiated by the serial bus master. The beginning of a data transfer is indicated by a start condition, which is signaled when the SDA line transitions to a low state while SCL is in the high state, as illustrated in Figure 3–10. The end of a requested data transfer is indicated by a stop condition, which is signaled by a low-to-high transition of SDA while SCL is in the high state, as shown in Figure 3–10. Data on SDA must remain stable during the high state of the SCL signal, as changes on the SDA signal during the high state of SCL are interpreted as control signals, that is, a start or a stop condition.

Data is transferred serially in 8-bit bytes. The number of bytes that can be transmitted during a data transfer is unlimited; however, each byte must be completed with an acknowledge bit. An acknowledge (ACK) is indicated by the receiver pulling the SDA signal low so that it remains low during the high state of the SCL signal. Figure 3–11 illustrates the acknowledge protocol.

The PCI1410A device is a serial bus master; all other devices connected to the serial bus external to the PCI1410A device are slave devices. As the bus master, the PCI1410A device drives the SCL clock at nearly 100 kHz during bus cycles and places SCL in a high-impedance state (zero frequency) during idle states.
Typically, the PCI1410A device masters byte reads and byte writes under software control. Doubleword reads are performed by the serial EEPROM initialization circuitry upon a PCI reset, and may not be generated under software control. See Section 3.6.3, Serial Bus EEPROM Application, for details on how the PCI1410A device automatically loads the subsystem identification and other register defaults through a serial bus EEPROM.
Figure 3–12 illustrates a byte write. The PCI1410A device issues a start condition and sends the 7-bit slave device address and the command bit 0. A 0 in the R/W
command bit indicates that the data transfer is a write. The slave device acknowledges if it recognizes the address. If there is no acknowledgment received by the PCI1410A device, an appropriate status bit is set in the serial bus control and status register (PCI offset B3h, see Section 4.50). The word address byte is then sent by the PCI1410A device and another slave acknowledgment is expected. The PCI1410A device then delivers the data byte, MSB first, and expects a final acknowledgment before issuing the stop condition.

3.6.3 Serial Bus EEPROM Application
When the PCI bus is reset and the serial bus interface is detected, the PCI1410A device attempts to read the subsystem identification and other register defaults from a serial EEPROM. The registers and corresponding bits that may be loaded with defaults through the EEPROM are provided in Table 3–6.

The byte at the EEPROM word address 00h must contain either a valid offset reference, as listed in Table 3–6, or an end-of-list (EOL) indicator. The EOL indicator has a byte value of FFh, and indicates the end of the data to load from the EEPROM. Only doubleword registers are loaded from the EEPROM, and all bit fields must be considered when programming the EEPROM.
The serial EEPROM is addressed at slave address 1010 000b by the PCI1410A device. All hardware address bits for the EEPROM should be tied to the appropriate level to achieve this address. The serial EEPROM chip in the sample application circuit (Figure 3–9) assumes the 1010b high address nibble. The lower three address bits are terminal inputs to the chip, and the sample application shows these terminal inputs tied to GND.
When a valid offset reference is read, four bytes are read from the EEPROM, MSB first, as illustrated in Figure 3–14. The address autoincrements after every byte transfer according to the doubleword read protocol. Note that the word addresses align with the data format illustrated in Figure 3–15. The PCI1410A device continues to load data from the serial EEPROM until an end-of-list indicator is read. Three reserved bytes are stuffed to maintain 8-byte data structures.
Note, the 8-byte data structure is important to provide correct addressing per the doubleword read format shown in Figure 3–14. In addition, the reference offsets must be loaded in the EEPROM in sequential order, that is, 01h, 02h, 03h, 04h. If the offsets are not sequential, the registers will be loaded incorrectly.
3.6.4 Accessing Serial Bus Devices Through Software
The PCI1410A device provides a programming mechanism to control serial bus devices through software. The programming is accomplished through a doubleword of PCI configuration space at offset B0h. Table 3–7 lists the registers used to program a serial bus device through software.

Serial bus slave address
Serial bus control and status
The content of this register is sent as the word address on byte writes or reads. This register is not used in the quick command protocol.
Write transactions to this register initiate a serial bus transaction. The slave device address and the R/W command selector are programmed through this register.
Read data valid, general busy, and general error status are communicated through this register. In addition, the protocol select bit is programmed through this register.
To write a byte, the serial bus data register must be programmed with the data, the serial bus index register must be programmed with t h e b yte address, and the serial bus slave address register must be programmed with the 7-bit slave address (SLAVADDR field) and bit 0 (RWCMD) must be reset.
On byte reads, the byte address is programmed into the serial bus index register, the serial bus slave address register must be programmed with the 7-bit slave address (SLAVADDR field) and bit 0 (RWCMD) must be set, and bit 5 (REQBUSY) in the serial bus control and status register (PCI offset B3h, see Section 4.50) must be polled until clear. Then the contents of the serial bus data register are valid read data from the serial bus interface.
3.7 Programmable Interrupt Subsystem
Interrupts provide a way for I/O devices to let the microprocessor know that they require servicing. The dynamic nature of PC Cards and the abundance of PC Card I/O applications require substantial interrupt support from the PCI1410A device. The PCI1410A device provides several interrupt signaling schemes to accommodate the needs of a variety of platforms. The different mechanisms for dealing with interrupts in this device are based on various specifications and industry standards. The ExCA register set provides interrupt control for some 16-bit PC Card functions, and the CardBus socket register set provides interrupt control for the CardBus PC Card functions. The PCI1410A device is, therefore, backward compatible with existing interrupt control register definitions, and new registers have been defined where required.
The PCI1410A device detects PC Card interrupts and events at the PC Card interface and notifies the host controller, using one of several interrupt signaling protocols. To simplify the discussion of interrupts in the PCI1410A device, PC Card interrupts are classified either as card status change (CSC) or as functional interrupts.
The method by which any type of PCI1410A interrupt is communicated to the host interrupt controller varies from system to system. The PCI1410A device offers system designers the choice of using parallel PCI interrupt signaling, parallel ISA-type IRQ interrupt signaling, or the IRQSER serialized ISA and/or PCI interrupt protocol. It is possible to use the parallel PCI interrupts in combination with either parallel IRQs or serialized IRQs, as detailed in the sections that follow. All interrupt signaling is provided through the seven multifunction terminals, MFUNC0–MFUNC6.
3.7.1 PC Card Functional and Card Status Change Interrupts
PC Card functional interrupts are defined as requests from a PC Card application for interrupt service and are indicated by asserting specially defined signals on the PC Card interface. Functional interrupts are generated by 16-bit I/O PC Cards and by CardBus PC Cards.
Card status change (CSC)-type interrupts are defined as events at the PC Card interface that are detected by the PCI1410A device, and may warrant notification of host card and socket services software for service. CSC events include both card insertion and removal from PC Card sockets, as well as transitions of certain PC Card signals.
Table 3–8 summarizes the sources of PC Card interrupts and the type of card associated with them. CSC and functional int e r r u p t sources are dependent on the type of card inserted in the PC Card socket. The three types of cards that can be inserted into any PC Card socket are:
16-bit memory cards
16-bit I/O cards
CardBus cards

Functional interrupt events are valid only for 16-bit I/O and CardBus cards; that is, the functional interrupts are not

valid for 16-bit memory cards. Furthermore, card insertion and removal-type CSC interrupts are independent of the card type.
Table 3–8. PC Card Interrupt Events and Description

A transition on BVD1 indicates a change in the PC Card battery conditions.
A transition on BVD2 indicates a change in the PC Card battery conditions.
A transition on READY indicates a change in the ability of the memory PC Card to accept or provide data.
The assertion of STSCHG indicates a status change on the PC Card.
The assertion of IREQ indicates an interrupt request from the PC Card.
The assertion of CSTSCHG indicates a status change on the PC Card.
The assertion of CINT indicates an interrupt request from the PC Card.
A transition on either CD1//CCD1 or CD2//CCD2 indicates an insertion or removal of a 16-bit or CardBus PC Card.

The naming convention for PC Card signals describes the function for 16-bit memory, I/O cards, and CardBus. For example, READY(IREQ
)//CINT includes READY for 16-bit memory cards, IREQ for 16-bit I/O cards, and CINT for CardBus cards. The 16-bit memory card signal name is first, with the I/O card signal name second, enclosed in parentheses. The CardBus signal name follows after a double slash (//).
The PC Card Standard describes the power-up sequence that must be followed by the PCI1410A device when an insertion event occurs and the host requests that the socket V
and VPP be powered. Upon completion of this
CC
power-up sequence, the PCI1410A interrupt scheme can be used to notify the host system (see Table 3–8), denoted by the power cycle complete event. This interrupt source is considered a PCI1410A internal event because it depends on the completion of applying power to the socket rather than on a signal change at the PC Card interface.
3.7.2 Interrupt Masks and Flags
Host software may individually mask (or disable) most of the potential interrupt sources listed in Table 3–8 by setting the appropriate bits in the PCI1410A device. By individually masking the interrupt sources listed, software can control those events that cause a PCI1410A interrupt. Host software has some control over the system interrupt the PCI1410A device asserts by programming the appropriate routing registers. The PCI1410A device allows host software to route PC Card CSC and PC Card functional interrupts to separate system interrupts. Interrupt routing is somewhat specific to the interrupt signaling method used. This is discussed in more detail in the following sections.
When an interrupt is signaled by the PCI1410A device, the interrupt service routine must determine which of the events listed in Table 3–9 caused the interrupt. Internal registers in the PCI1410A device provide flags that report the source of an interrupt. By reading these status bits, the interrupt service routine can determine the action to be taken.
Table 3–9 details the registers and bits associated with masking and reporting potential interrupts. All interrupts can be masked, except the functional PC Card interrupts, and an interrupt status flag is available for all types of interrupts.

Notice that there is not a mask bit to stop the PCI1410A device from passing PC Card functional interrupts through to the appropriate interrupt scheme. These interrupts are not valid until the card is properly powered, and there never should be a card interrupt that does not require service after proper initialization.
Table 3–9 lists the various methods of clearing the interrupt flag bits. The flag bits in the ExCA registers (16-bit PC Card-related interrupt flags) can be cleared using two different methods. One method is an explicit write of 1 to the flag bit to clear, and the other is by reading the flag bit register. The selection of flag bit clearing is made by bit 2 (IFCMODE) in the ExCA global control register (ExCA offset 1Eh, see Section 5.20) and defaults to the flag cleared on read method.
The CardBus-related interrupt flags can be cleared by an explicit write of 1 to the interrupt flag in the socket force event register (CardBus offset 0Ch, see Section 6.4). Although some of the functionality is shared between the CardBus registers and the ExCA registers, software should not program the chip through both register sets when a CardBus card is functioning.
3.7.3 Using Parallel IRQ Interrupts
The seven multifunction terminals, MFUNC6–MFUNC0, implemented in the PCI1410A device may be routed to obtain a subset of the ISA IRQs . The IRQ choices provide ultimate flexibility in PC Card host interruptions. To use the parallel ISA type IRQ interrupt signaling, software must program the device control register (PCI offset 92h, see Section 4.33), to select the parallel IRQ signaling scheme. See Section 4.30, Multifunction Routing Register, for details on configuring the multifunction terminals.
A system using parallel IRQs requires a minimum of one PCI terminal, INTA is dictated by certain card and socket services software. The INTA for INTA
signaling. This leaves (at a maximum) six different IRQs to support legacy 16-bit PC Card functions.
requirement calls for routing the MFUNC0 terminal
As an example, suppose the six IRQs used by legacy PC Card applications are IRQ3, IRQ4, IRQ5, IRQ10, IRQ11, and IRQ15. The multifunction routing register must be programmed to a value of 0FBA 5432h. This value routes the MFUNC0 terminal to INTA that INTA
also must be routed to the programmable interrupt controller (PIC), or to some circuitry that provides parallel
signaling and routes the remaining terminals as illustrated in Figure 3–16. Not shown is

Power-on software is responsible for programming the multifunction routing register to reflect the IRQ configuration of a system implementing the PCI1410A device. See Section 4.30, Multifunction Routing Register,
for details on
configuring the multifunction terminals. The parallel ISA-type IRQ signaling from the MFUNC6–MFUNC0 terminals is compatible with those input directly into
the 8259 PIC. The parallel IRQ option is provided for system designs that require legacy ISA IRQs. Design constraints may demand more MFUNC6–MFUNC0 IRQ terminals than the PCI1410A device makes available.
3.7.4 Using Parallel PCI Interrupts
Parallel PCI interrupts are available when exclusively in parallel PCI interrupt mode, parallel ISA IRQ signaling mode, and when only IRQs are serialized with the IRQSER protocol. The socket function interrupts are routed to INTA (MFUNC0).
3.7.5 Using Serialized IRQSER Interrupts
The serialized interrupt protocol implemented in the PCI1410A device uses a single terminal to communicate all interrupt status information to the host controller. The protocol defines a serial packet consisting of a start cycle, multiple interrupt indication cycles, and a stop cycle. All data in the packet is synchronous with the PCI clock. The packet data describes 16 parallel ISA IRQ signals and the optional 4 PCI interrupts INTA
, INTB, INTC, and INTD. For
details on the IRQSER protocol, refer to the document Serialized IRQ Support for PCI Systems.
3.7.6 SMI Support in the PCI1410A Device
The PCI1410A device provides a mechanism for interrupting the system when power changes have been made to the PC Card socket interfaces. The interrupt mechanism is designed to fit into a system maintenance interrupt (SMI) scheme. SMI interrupts are generated by the PCI1410A device, when enabled, after a write cycle to either the socket control register (CardBus offset 10h, see Section 6.5) of the CardBus register set or the ExCA power control register (ExCA of fs et 02h, see Section 5.3) causes a power cycle change sequence to be sent on the power-switch interface.
The SMI control is programmed through three bits in the system control register (PCI offset 80h, see Section 4.29). These bits are SMIROUTE (bit 26), SMISTATUS (bit 25), and SMIENB (bit 24). Table 3–10 describes the SMI control bits function.
Table 3–10. SMI Control
BIT NAME FUNCTION
SMIROUTE This shared bit controls whether the SMI interrupts are sent as a CSC interrupt or as IRQ2. SMISTATUS This socket-dependent bit is set when an SMI interrupt is pending. This status flag is cleared by writing back a 1. SMIENB When set, SMI interrupt generation is enabled.
If CSC SMI interrupts are selected, the SMI interrupt is sent as the CSC. The CSC interrupt can be either level or edge mode, depending upon bit 1 (CSCMODE) in the ExCA global control register (ExCA offset 1Eh, see Section 5.20).
If IRQ2 is selected by SMIROUTE, the IRQSER signaling protocol supports SMI signaling in the IRQ2 IRQ/Data slot. In a parallel ISA IRQ system, the support for an active low IRQ2 is provided only if IRQ2 is routed to either MFUNC1, MFUNC3, or MFUNC6 through the multifunction routing register (PCI offset 8Ch, see Section 4.30).

3.8 Power-Management Overview
In addition to the low-power CMOS technology process used for the PCI1410A device, various features are designed into the device to allow implementation of popular power-saving techniques. These features and techniques are discussed in this section.
3.8.1 Clock-Run Protocol
The PCI CLKRUN feature is the primary method of power management on the PCI interface of the PCI1410A device. CLKRUN this is not always available to the system designer, and alternate power-saving features are provided. For details on the CLKRUN
The PCI1410A device does not permit the central resource to stop the PCI clock under any of the following conditions:
The PCI1410A device restarts the PCI clock using the CLKRUN protocol under any of the following conditions:
signaling is provided through the MFUNC6 terminal. Because some chipsets do not implement CLKRUN,

manager.
3.8.2 CardBus PC Card Power Management
The PCI1410A device implements its own card power-management engine that can turn off CCLK to a socket when there is no activity to the CardBus PC Card. The PCI clock-run protocol is followed on the CardBus CCLKRUN interface to control this clock management.
3.8.3 16-Bit PC Card Power Management
Bit 7 (COE) in the ExCA power control register (ExCA offset 02h, see Section 5.3) and bit 0 (PWRDWN) in the ExCA global control register (ExCA offset 1Eh, see Section 5.20) are provided for 16-bit PC Card power management. The COE bit places the card interface in a high-impedance state to save power. The power savings when using this feature are minimal. The COE bit will reset the PC Card when used, and the PWRDWN bit will not. Furthermore, the PWRDWN bit is an automatic COE, that is, the PWRDWN performs the COE function when there is no card activity.
NOTE: The 16-bit PC Card must implement the proper pullup resistors for the COE and PWRDWN modes.
3–19
3.8.4 Suspend Mode
The SUSPEND signal, provided for backward compatibility, gates the PRST (PCI reset) signal and the GRST (global reset) signal from the PCI1410A device. Besides gating PRST PCI1410A device to minimize power consumption.
Gating PCLK does not create any issues with respect to the power-switch interface in the PCI1410A device. This is because the PCI1410A device does not depend on the PCI clock to clock the power-switch interface. There are two methods to clock the power-switch interface in the PCI1410A device:
Use an external clock to the PCI1410A PCLK terminal.
Use the internal oscillator.
and GRST, SUSPEND also gates PCLK inside the
It also should be noted that asynchronous signals, such as card status-change interrupts and RI_OUT
, can be passed to the host system without a PCI clock. However, if card status-change interrupts are routed over the serial interrupt stream, the PCI clock must be restarted to pass the interrupt, because neither the internal oscillator nor an external clock is routed to the serial interrupt state machine. Figure 3–17 shows the suspend logic diagram.

3.8.5 Requirements for Suspend Mode
The suspend mode prevents the clearing of all register contents on the assertion of reset (PRST or GRST) that would require the reconfiguration of the PCI1410A device by software. Asserting the SUSPEND
signal places the controller PCI outputs in a high-impedance state and gates the PCLK signal internally to the controller unless a PCI transaction currently is in process (GNT SUSPEND
is asserted, because the outputs are in a high-impedance state.

signals are all active during SUSPEND, unless they are disabled in the
appropriate PCI1410A registers.
3.8.6 Ring Indicate
The RI_OUT output is an important feature in power management, allowing a system to go into a suspended mode and wake up on modem rings and other card events. TI-designed flexibility permits this signal to fit wide platform requirements. RI_OUT

, is enabled through the same mask as the CSC event for CSTSCHG. The mask bit (bit 0, CSTSMASK) is programmed through the socket mask register (CardBus offset 04h, see Section 6.2) in the CardBus socket registers.
3.8.7 PCI Power Management
The PCI Bus Power Management Interface Specification for PCI to CardBus Bridges establishes the infrastructure required for the operating system to control the power of PCI functions. This is done by defining a standard PCI interface and operations to manage the power of PCI functions on the bus. The PCI bus and the PCI functions can be assigned one of four software-visible power-management states that result in varying levels of power savings.
The four power-management states of PCI functions are:
D0 Fully-on state
D1 and D2 Intermediate states
D3 Off state
Similarly , b u s power states of the PCI bus are B0–B3. The bus power states B0–B3 are derived from the device power state of the originating bridge device.
For the operating system (OS) to manage the device power states on the PCI bus, the PCI function must support four power-management operations. These operations are:
Capabilities reporting
Power status reporting
Setting the power state
System wake-up
The OS identifies the capabilities of the PCI function by traversing the new capabilities list. The presence of capabilities, in addition to the standard PCI capabilities, is indicated by a 1 in bit 4 (CAPLIST) of the status register (PCI offset 06h, see Section 4.5).
The capabilities pointer provides access to the first item in the linked list of capabilities. For the PCI1410A device, a CardBus bridge with PCI configuration space header type 2, the capabilities pointer is mapped to an offset of 14h. The first byte of each capability register block is required to be a unique ID of that capability. PCI power management has been assigned an ID of 01h. The next byte is a pointer to the next pointer item in the list of capabilities. If there are no more items in the list, the next item pointer should be set to 0. The registers following the next item pointer are specific to the capabilities of their corresponding power-management functions. The PCI power-management capability implements the register block outlined in Table 3–11.
3–22

PM data PMCSR bridge support extensions Power management control/status A4h
The power management capabilities register (PCI offset A2h, see Section 4.39) provides information on the capabilities of the function related to power management. The power management control/status register (PCI offset A4h, see Section 4.40) enables control of power management states and enables/monitors power management events. The data register is an optional register that can provide dynamic data.
For more information on PCI power management, see the PCI Bus Power Management Interface Specification for PCI to CardBus Bridges.
3.8.8 CardBus Device Class Power Management
The PCI Bus Power Management Interface Specification for PCI to CardBus Bridges was approved by PCMCIA in December of 1997. This specification follows the device and bus state definitions provided in the PCI Bus Power Management Interface Specification published by the PCI Special Interest Group (SIG). The main issue addressed in the PCI Bus Power Management Interface Specification for PCI to CardBus Bridges is wake-up from D3 without losing wake-up context (also called PME context).
The specific issues addressed by the PCI Bus Power Management Interface Specification for PCI to CardBus Bridges for D3 wake up are as follows:
Preservation of device context: The specification states that a reset must occur when transitioning from D3 to D0. Some method to preserve wake-up context must be implemented so that the reset does not clear the PME
context registers.

3.8.9 ACPI Support
The Advanced Configuration and Power Interface (ACPI) Specification provides a mechanism that allows unique pieces of hardware to be described to the ACPI driver. The PCI1410A device offers a generic interface that is compliant with ACPI design rules.
Two doublewords of general-purpose ACPI programming bits reside in PCI1410A PCI configuration space at offset A8h. The programming model is broken into status and control functions. In compliance with ACPI, the top-level event status and enable bits reside in the general-purpose event status (PCI offset A8h, see Section 4.43) and general-purpose event enable (PCI offset AAh, see Section 4.44) registers. The status and enable bits are implemented as defined by ACPI and illustrated in Figure 3–20.
3–23
Status Bit
Event Input
Enable Bit
Event Output
Figure 3–20. Block Diagram of a Status/Enable Cell
The status and enable bits generate an event that allows the ACPI driver to call a control method associated with the pending status bit. The control method can then control the hardware by manipulating the hardware control bits or by investigating child status bits and calling their respective control methods. A hierarchical implementation would be somewhat limiting, however, as upstream devices would have to remain in some level of power state to report events.
For more information on ACPI, see the Advanced Configuration and Power Interface (ACPI) Specification.

A bit description table, typically included when a register contains bits of more than one type or purpose, indicates bit field names, a detailed field description, and field access tags, which appear in the type column of the bit-description table. Table 4–2 describes the field access tags.
Table 4–2. Bit-Field Access Tag Descriptions

R Read Field can be read by software.
W Write Field can be written by software to any value.
S Set Field can be set by a write of 1. Writes of 0 have no effect. C Clear Field can be cleared by a write of 1. Writes of 0 have no effect. U Update Field can be autonomously updated by the PCI1410A device.
A bit can display either of two types of behavior when read. After having been read, it can maintain the value it had previously, or the read process can cause it to be reset to 0.

Fast back-to-back enable. The PCI1410A device does not generate fast back-to-back transactions; therefore, bit 9 returns 0 when read.
System error (SERR) enable. Bit 8 controls the enable for the SERR driver on the PCI interface. SERR can be asserted after detecting an address parity error on the PCI bus. Both bits 8 and 6 must be set for the PCI1410A device to report address parity errors.

Address/data stepping control. The PCI1410A device does not support address/data stepping; therefore, bit 7 is hardwired to 0.

0 = PCI1410A device ignores detected parity error (default). 1 = PCI1410A device responds to detected parity errors.
VGA palette snoop. When bit 5 is set to 1, palette snooping is enabled (that is, the PCI1410A device does not respond to palette register writes and snoops the data). When bit 5 is 0, the PCI1410A device treats all palette accesses like all other accesses.
Memory write and invalidate enable. Bit 4 controls whether a PCI initiator device can generate memory write and invalidate commands. The PCI1410A controller does not support memory write and invalidate commands. It uses memory write commands instead; therefore, this bit is hardwired to 0.
Special cycles. Bit 3 controls whether or not a PCI device ignores PCI special cycles. The PCI1410A device does not respond to special cycle operations; therefore, this bit is hardwired to 0.
Bus-master control. Bit 2 controls whether or not the PCI1410A device can act as a PCI bus initiator (master). The PCI1410A device can take control of the PCI bus only when this bit is set.

Fast back-to-back capable. The PCI1410A device cannot accept fast back-to-back transactions; therefore, bit 7 is hardwired to 0.
User-definable feature support. The PCI1410A device does not support the user-definable features; therefore, bit 6 is hardwired to 0.

4.12 CardBus Socket/ExCA Base-Address Register
The CardBus socket/ExCA base-address register is programmed with a base address referencing the CardBus socket registers and the memory-mapped ExCA register set. Bits 31–12 are read/write and allow the base address to be located anywhere in the 32-bit PCI memory address space on a 4-Kbyte boundary. Bits 11–0 are read-only, returning 0s when read. When software writes all 1s to this register, the value read back is FFFF F000h, indicating that at least 4 Kbytes of memory address space are required. The CardBus registers start at offset 000h, and the memory-mapped ExCA registers begin at offset 800h.

4.18 CardBus Latency Timer Register
This register is programmed by the host system to specify the latency timer for the PCI1410A CardBus interface in units of CCLK cycles. When the PCI1410A device is a CardBus initiator and asserts CFRAME
, the CardBus latency timer begins counting. If the latency timer expires before the PCI1410A transaction has terminated, the PCI1410A device terminates the transaction at the end of the next data phase. A recommended minimum value for this register is 20h, which allows most transactions to be completed.

4.19 Memory Base Registers 0, 1
The memory base registers indicate the lower address of a PCI memory address range. These registers are used by the PCI1410A device to determine when to forward a memory transaction to the CardBus bus and when to forward a CardBus cycle to the PCI bus. Bits 31–12 of these registers are read/write and allow the memory base to be located anywhere in the 32-bit PCI memory space on 4-Kbyte boundaries. Bits 11–0 are read-only and always return 0s. Write transactions to these bits have no effect. Bits 8 (PREFETCH0) and 9 (PREFETCH1) of the bridge control register (PCI offset 3Eh, see Section 4.25) specify whether memory windows 0 and 1 are prefetchable or nonprefetchable. The memory base register or the memory limit register must be nonzero for the PCI1410A device to claim any memory transactions through the CardBus memory windows (that is, these windows are not enabled by default to pass the first 4 Kbytes of memory to CardBus).

4.21 I/O Base Registers 0, 1
The I/O base registers indicate the lower address of a PCI I/O address range. These registers are used by the PCI1410A device to determine when to forward an I/O transaction to the CardBus bus and when to forward a CardBus cycle to the P C I bus. The lower 16 bits of these registers locate the bottom of the I/O window within a 64-Kbyte page, and the upper 16 bits (31–16) are a page register that locates this 64-Kbyte page in 32-bit PCI I/O address space. Bits 31–2 are read/write. Bits 1 and 0 are read-only and always return 0s, forcing the I/O window to be aligned on a natural doubleword boundary.
NOTE: Either the I/O base or the I/O limit register must be nonzero to enable any I/O transactions.

The lower 16 bits of these registers locate the top of the I/O window within a 64-Kbyte page, and the upper 16 bits are a page register that locates this 64-Kbyte page in 32-bit PCI I/O address space. Bits 15–2 are read/write and allow the I/O limit address to be located anywhere in the 64-Kbyte page (indicated by bits 31–16 of the appropriate I/O base register) on doubleword boundaries.
Bits 31–16 are read-only and always return 0s when read. The page is set in the I/O base register. Bits 1 and 0 are read-only and always return 0s, forcing I/O windows to be aligned on a natural doubleword boundary. Write transactions to read-only bits have no effect. The PCI1410A device assumes that the lower 2 bits of the limit address are 1s.

5 ExCA Compatibility Registers
The ExCA registers implemented in the PCI1410A device are register-compatible with the Intel 82365SL–DF PCMCIA controller. The ExCA registers are identified by an offset value that is compatible with the legacy I/O index/data scheme used on the Intel 82365 ISA controller. The ExCA registers are accessed through this scheme by writing the register offset value into the index register (I/O base) and reading or writing the data register (I/O base + 1). The I/O base address used in the index/data scheme is programmed in the PC Card 16-bit I/F legacy mode base address register (PCI offset 44h, see Section 4.28). The offsets from this base address run contiguous from 00h to 3Fh for the socket. See Figure 5–1 for an ExCA I/O-mapping illustration.

The TI PCI1410A device also provides a memory-mapped alias of the ExCA registers by directly mapping them into PCI memory space. They are located through the CardBus socket/ExCA base address register (PCI offset 10h, see Section 4.12) at memory of fset 800h. See Figure 5–2 for an ExCA memory-mapping illustration. This illustration also identifies the CardBus socket-register mapping, which is mapped into the same 4K window at memory offset 0h.

The interrupt registers in the ExCA register set, as defined by the 82365SL–DL specification, control such card functions as reset, type, interrupt routing, and interrupt enables. Special attention must be paid to the interrupt routing registers and the host-interrupt signaling method selected for the PCI1410A device to ensure that all possible PCI1410A interrupts potentially can be routed to the programmable interrupt controller. The ExCA registers that are critical to the interrupt signaling are the ExCA interrupt and general control register (ExCA offset 03h, see Section 5.4) and the ExCA card status-change-interrupt configuration register (ExCA offset 05h, see Section 5.6).
Access to I/O-mapped 16-bit PC cards is available to the host system via two ExCA I/O windows. These are regions of host I/O address space into which the card I/O space is mapped. These windows are defined by start, end, and offset addresses programmed in the ExCA registers described in this section. I/O windows have byte granularity.
Access to memory-mapped 16-bit PC Cards is available to the host system via five ExCA memory windows. These are regions of host memory space into which the card memory space is mapped. These windows are defined by start, end, and offset addresses programmed in the ExCA registers described in this section. Table 5–1 identifies each ExCA register and its respective ExCA offset. Memory windows have 4-Kbyte granularity.

5.3 ExCA Power Control Register
The ExCA power control register provides PC Card power control. Bit 7 (COE) of this register controls the 16-bit output enables on the socket interface, and can be used for power management in 16-bit PC Card applications. The PCI1410A device supports both the 82365SL and 82365SL-DF register models. Bits 3–0 (365REV filed) of the ExCA identification and revision register (ExCA offset 00h, see Section 5.1) control which register model is supported. See Table 5–4 and Table 5–5 for a complete description of the register contents.
