Hi-Speed Universal Serial Bus PCI Host Controller

Rev. 01 — 14 July 2005 Product data sheet

1. General description

The ISP1563 is a Peripheral Component Interconnect (PCI)-based, single-chip Universal Serial Bus (USB) Host Controller. It integrates two Original USB Open Host Controller Interface (OHCI) cores, one Hi-Speed USB Enhanced Host Controller Interface (EHCI) core, and four transceivers that are compliant with Hi-Speed USB and Original USB. The functional parts of the ISP1563 are fully compliant with

Rev. 2.0,Open Host Controller Interface Speciﬁcation for USB Rev. 1.0a,Enhanced Host Controller Interface Speciﬁcation for Universal Serial Bus Rev. 1.0,PCI Local Bus Speciﬁcation Rev. 2.2

The integrated high performance USB transceivers allow the ISP1563 to handle all Hi-Speed USB transfer speed modes: high-speed (480 Mbit/s), full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s). The ISP1563 provides four downstream ports, allowing simultaneous connection of USB devices at different speeds.

Universal Serial Bus Speciﬁcation

, and

PCI Bus Power Management Interface Speciﬁcation Rev. 1.1

The ISP1563 provides downstream port status indicators, green and amber LEDs, to allow user-rich messages of the Root Hub downstream ports status, without requiring detailed port information in the internal registers.

The ISP1563 is fully compatible with various operating system drivers, such as Microsoft Windows standard OHCI and EHCI drivers that are present in Windows XP, Windows 2000 and Red Hat Linux.

The ISP1563 directly interfaces to any 32-bit, 33 MHz PCI bus. Its PCI pins can source

3.3 V. The PCI interface fully complies with The ISP1563 is ideally suited for use in Hi-Speed USB host-enabled motherboards,

Hi-Speed USB host PCI add-on card applications, mobile applications, and embedded solutions.

To facilitate motherboard development, the ISP1563 can use the available 48 MHz clock signal to reduce the total cost of a solution. To reduce Electro-Magnetic Interference (EMI), however, it is recommended that the 12 MHz crystal is used in PCI add-on card designs.

7. Functional description

7.1 OHCI Host Controller

An OHCI Host Controller transfers data to devices at the Original USB deﬁned bit rate of 12 Mbit/s or 1.5 Mbit/s.

7.2 EHCI Host Controller

The EHCI Host Controller transfers data to a Hi-Speed USB compliant device at the Hi-Speed USB deﬁned bit rate of 480 Mbit/s. When the EHCI Host Controller has the ownership of a port, the OHCI Host Controllers are not allowed to modify the port register. All additional port bit deﬁnitions required for the Enhanced Host Controller are not visible to the OHCI Host Controller.

7.3 Dynamic port-routing logic

The port-routing feature allows sharing of the same physical downstream ports between the Original USB Host Controller and the Hi-Speed USB Host Controller. This requirement of the

Enhanced Host Controller Interface Speciﬁcation for Universal Serial Bus Rev. 1.0

provides four downstream ports, and these ports are multiplexed with the ports of the two OHCIs. The ﬁrst and third downstream ports are always connected to the ﬁrst OHCI, and the second and fourth downstream ports are always connected to the second OHCI.

ISP1563

HS USB PCI Host Controller

The EHCI is responsible for the port-routing switching mechanism. Two register bits are used for ownership switching. During power-on and system reset, the default ownership of all downstream ports is the OHCI. The Enhanced Host Controller Driver (HCD) controls the ownership during normal functionality.

7.4 Hi-Speed USB analog transceivers

The Hi-Speed USB analog transceivers directly interface to the USB cables through integrated termination resistors. These transceivers can transmit and receive serial data at all data rates: high-speed (480 Mbit/s), full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s).

7.5 LED indicators for downstream ports

The system designer can program two optional port indicators, a green LED and an amber LED, to indicate the status of the Host Controller. These port indicators are implemented according to the USB speciﬁcation.

All LED indicators are open-drain output.

7.6 Power management

The ISP1563 provides an advanced power management capability interface that is compliant with controlled and managed by the interaction between drivers and PCI registers.

7.7 Legacy support

The ISP1563 provides legacy support for a USB keyboard and mouse. This means that the keyboard and mouse should be able to work even before the Operating System (OS) boot-up, with the necessary support in the Basic Input Output System (BIOS).

Section 11.2 provides a detailed description on the legacy support in the ISP1563.

7.8 Phase-Locked Loop (PLL)

A 12 MHz-to-30 MHz and 48 MHz clock multiplier PLL is integrated on-chip. This allows the use of a low-cost 12 MHz crystal, which also minimizes EMI. No external components are required for the PLL to operate.

8.1 PCI interface

The PCI interface has three functions. The ﬁrst function (#0) and the second function (#1) are for the OHCI Host Controllers, and the third function (#2) is for the EHCI Host Controller. All functions support both master and target accesses, and share the same PCI interrupt signal INTA#. These functions provide memory-mapped, addressable operational registers as required in

Additionally, function #0 provides legacy keyboard and mouse support to comply with

Open Host Controller Interface Speciﬁcation for USB Rev. 1.0a

Each function has its own conﬁguration space. The PCI enumerator should allocate the memory address space for each of these functions. Power management is implemented in each PCI function and all power states are provided. This allows the system to achieve low power consumption by switching off the functions that are not required.

8.1.1 PCI conﬁguration space

ISP1563

HS USB PCI Host Controller

PCI Local Bus Speciﬁcation Rev. 2.2

ISP1563 provides its own PCI conﬁguration registers, which can vary in size. In addition to the basic PCI conﬁguration header registers, these functions implement capability registers to support power management.

The registers of each of these functions are accessed by the respective driver.Section 8.2 provides a detailed description of the various PCI conﬁguration registers.

8.1.2 PCI initiator and target

A PCI initiator initiates PCI transactions to the PCI bus. A PCI target responds to PCI transactions as a slave. In the case of the ISP1563, the two Open Host Controllers and the Enhanced Host Controller function as both initiators or targets of PCI transactions issued by the host CPU.

All USB Host Controllers havetheir own operational registers that can be accessed by the system driver software. Drivers use these registers to conﬁgure the Host Controller hardware system, issue commands to it, and monitor the status of the current hardware operation. The Host Controller plays the role of a PCI target. All operational registers of the Host Controllers are the PCI transaction targets of the CPU.

Normal USB transfers require the Host Controller to access system memory ﬁelds, which are allocated by USB HCDs and PCI drivers. The Host Controller hardware interacts with the HCD by accessing these buffers. The Host Controller works as an initiator in this case, and becomes a PCI master.

requires that each of the three PCI functions of the

8.2 PCI conﬁguration registers

The OHCI USB Host Controllers and the EHCI USB Host Controller contain two sets of software-accessible hardware registers: PCI conﬁguration registers and memory-mapped Host Controller registers.

A set of conﬁguration registers is implemented for each of the three PCI functions of the ISP1563, see Table 3.

Remark: In addition to the normal PCI header, from offset index 00h to 3Fh, implementation-speciﬁc registers are deﬁned to support power management and function-speciﬁc features.

8.2.1.6 Class Code register

Class Code is a 24-bit read-only register used to identify the generic function of the device, and in some cases, a speciﬁc register-level programming interface. Table 11 shows the bit allocation of the register.

The Class Code register is divided into three byte-size ﬁelds. The upper byte is a base class code that broadly classiﬁes the type of function the device performs. The middle byte is a sub-class code that identiﬁes more speciﬁcally the function of the device. The lower byte identiﬁes a speciﬁc register-level programming interface, if any, so that device-independent software can interact with the device.

8.2.1.10 Base Address register 0

Power-up software must build a consistent address map beforebooting the machine to an operating system. This means it must determine how much memory is in the system, and how much address space the I/O controllers in the system require. After determining this information, power-up software can map the I/O controllers into reasonable locations and proceed with system boot. To do this mapping in a device-independent manner, the base registers for this mapping are placed in the predeﬁned header portion of conﬁguration space.

Bit 0 in all Base Address registers is read-only and used to determine whether the register maps into memory or I/O space. Base Address registers that map to memory space must return logic 0 in bit 0. Base Address registers that map to I/O space must return logic 1 in bit 0.

This is a read and write register at address 40h. The default and recommended value is 00h; TRDY Timeout disabled. This value can, however, be modiﬁed. It is an implementation-speciﬁc register, and not a standard PCI conﬁguration register.

The TRDY timer is 13 bits. The lower 5 bits are ﬁxed as logic 0 and the upper 8 bits are determined by the TRDY Timeout register value. The time-out is calculated by multiplying the 13-bit timer with the PCI CLK cycle time.

This register determines the maximum TRDY delay without asserting the UE (Unrecoverable Error) bit. If TRDY is longer than the delay determined by this register value, then the UE bit will be set.

Max_Lat: It is used to specify how often the device needs to gain access to the PCI bus.

8.2.1.18 Retry Timeout register

The default value of this read and write register is 80h, and is located at address 41h. This value can, however, be modiﬁed. Programming this register as 00h means that retry time-out is disabled. This is an implementation-speciﬁc register, and not a standard PCI conﬁguration register.

The time-out is determined by multiplying the register value with the PCI CLK cycle time. This register determines the maximumnumber of PCI retires before the UE bit is set. If the number of retries is longer than the delay determined by this register value, then the UE bit will be set.

8.2.2 Enhanced Host Controller-speciﬁc PCI registers

In addition to the PCI conﬁguration header registers, EHCI needs some additional PCI conﬁguration space registers to indicate the serial bus release number, downstream port wake-up event capability, and adjust the USB bus frame length for Start-of-Frame (SOF). The EHCI-speciﬁc PCI registers are given in Table 25.

8.2.2.3 PORTWAKECAP register

Port Wake Capability (PORTWAKECAP) is a 2 B register used to establish a policy about which ports are for wake events; see Table 29. Bit positions 15 to 1 in the mask correspond to a physical port implemented on the current EHCI controller. Logic 1 in a bit position indicates that a device connected below the port can be enabled as a wake-up device and the port may be enabled for disconnect or connect, or overcurrent events as wake-up events. This is an information only mask register. The bits in this register do not affect the actual operation of the EHCI Host Controller. The system-speciﬁc policy can be
