The PCI cards (or CompactPCI cards) are equipped with plug and play PCI
controller, it can request base addresses and interrupt according to PCI
standard. The system BIOS will install the system resource based on the
PCI cards’ configuration registers and system parameters (which are set by
system BIOS). Interrupt assignment and memory usage (I/O port locations)
of the PCI cards can be assigned by system BIOS only. These system
resource assignments are done on a board-by-board basis. It is not
suggested to assign the system resource by any other methods.
PCI slot selection
The PCI card can be inserted to any PCI slot without any configuration for
system resource.
Installation Procedures
1 Turn off your computer
2 Turn off all accessories (printer, modem, monitor, etc.) connected to

2.7 Jumpers’ Description
The PCI-7396 is a ‘plug and play’ add-on card using PCI bus. It is unnecessary for user to setup its base address and IRQ level to fit the
hardware of your computer system. However, to fit users’ versatile operation,
there are still a few jumpers to set the power-on-states of all I/O ports.
2.7.1 Power-on-state
For all I/O ports of the PCI-7396, the power-on-states could be pulled high,
pulled low, or floating. It is depended on the jumper settings. Table 2.1 lists
the reference numbers of jumpers and their corresponding port names.
All the jumpers are identical physically. The power-on-state of each port can
be set independently. To pull all signals low is the default settings. The
following diagram use JA1 as an example to show the possible settings.
Port A of PPI1 is pulled low.(default setting)
JA1
Port A of PPI1 is pulled high.
When the jumper cap is removed, the power-on-state is floating.

Registers Format
The detailed descriptions of the registers format are specified in this chapter.
This information is quite useful for the programmers who wish to handle the
card by low-level programming. However, we suggest user have to
understand more about the PCI interface then start any low-level
programming. In addition, the contents of this chapter can help users
understand how to use software driver to manipulate this card.
3.1 PCI PnP Registers
This PCI card functions as a 32-bit PCI target device to any master on the
PCI bus. There are three types of registers: PCI Configuration Registers
(PCR), Local Configuration Registers (LCR) and PCI-6308 registers.
The PCR, which is compliant to the PCI-bus specifications, is initialized and
controlled by the plug & play (PnP) PCI BIOS. User‘s can study the PCI
BIOS specification to understand the operation of the PCR. Please contact
with PCISIG to acquire the specifications of the PCI interface.
The PCI bus controller PCI-9050 is provided by PLX technology Inc.
(www.plxtech.com). For more detailed information of LCR, please visit PLX
technology’s web site to download relative information. It is not necessary
for users to understand the details of the LCR if you use the software library.
The PCI PnP BIOS assigns the base address of the LCR. The assigned
address is located at offset 14h of PCR.
The PCI-6308 registers are shown in the next section. The base address,
which is also assigned by the PCI PnP BIOS, is located at offset 18h of
PCR. Therefore, users can read the 18h of PCR to know the base address
by using the BIOS function call.

Please do not try to modify the base address and interrupt which assigned
by the PCI PnP BIOS, it may cause resource confliction in your system.

Figure 4.3 Timer / counter system of PCI-7396.
Timer #1 and timer #2 of the 8254 chip are cascaded as a 32-bits
programmable timer. In the software library, timer #1 and #2 are always set
as mode 2 (rate generator). Counter #0 is used as an event counter, that is,
there is an interrupt on the terminal count of 8254 mode 0.
4.2.2 Cascaded 32 bits Timer
The base frequency of input clock for the cascaded timer is 2MHz. The
output is send to be the timer interrupt. To set the maximum and minimum
frequency of the timer, please refer to the function _7348_Cascaded_Timer
or _7396_Cascaded_Timer.
4.2.3 Event Counter and Edge Control
The counter #0 of 8254 is used to be an event counter. The input is pin-51
of CN1. The trigger edge of counter clock is programmable. The gate
control fixs high (enable). The output is send to be the event interrupt. That
means If counter #0 is set as 8254 mode 0, the event IRQ asserts as the
counter counts down to zero.

4.3.1 System Architecture
The PCI-7396‘s interrupt system is powerful and flexible, which is suitable
for many applications. It is a Dual Interrupt System. The dual interrupt
means the hardware can generate two interrupt request signals in the same
time and the software can service these two request signals by ISR. Note
that the dual interrupt do not mean the card occupy two IRQ levels.
The two interrupt request signals (INT1 and INT2) comes from digital inputs
or the timer/counter outputs. Two multiplexers (MUX) are used to select the
IRQ sources. Fig 4.4 shows the interrupt system.
4.3.2 IRQ Level Setting
There is only one IRQ level needed in the PCI-7396, although it is a dual
interrupt system. This card uses INT #A interrupt request signal on PCI bus.
The mother board circuits will transfer INT #A to one of the AT bus IRQ
levels. The IRQ level is set by the PCI plug and play BIOS and saved in the
PCI controller. It is not necessary for users to set the IRQ level. Users can
get the IRQ level by software library.

4.3.3 Dual Interrupt System
The PCI controller can receive two hardware IRQ requests. However, only
one IRQ will be sent to PCI bus, the two IRQ requests must be
distinguished by user’s interrupt service routine (ISR).
The two IRQ requests are named as INT1 and INT2. INT1 comes from COS
P1 & P2, P1C0, P1C3, or the event counter interrupt. INT2 comes from
COS P3 & P4, P2C0, P2C3, or the timer interrupt. The sources of INT1 and
INT2 is selectable by using the Interrupt Source Control (ISC) Register.

4.3.4 Interrupt Source Control (ISC)
There are four bits to control the IRQ sources of INT1 and INT2. Table 4.1
shows the selection of the IRQ sources and the interrupt trigger condition.
If the application needs one IRQ only, you can disable one of the IRQ
sources by software. You can also disable both the two interrupts If you do
not need any IRQ source. However, the PCI BIOS still assign a IRQ level to
the PCI card and occupy the PC resource if you only disable the IRQ
sources without change the initial condition of the PCI controller.

P1A0
By using the four signals: P1C0, P2C0, P1C3, and P2C3, user can utilize
their combination to generate a proper IRQ for versatile applications.
4.3.5 Change of State (COS) Interrupt
What is COS?
The COS (Change of State) means when the input state (logic level) is
changed from low to high, or from high to low. The COS detection circuit will
detect the edge of level change. In the PCI-7396 card, the COS detection
circuit is applied to all the input channels. When any channel changes its
logic level, the COS detection circuit generates an interrupt request to PCI
controller.
COS Detection
The following timing is an example of COS operation. All the DI signals’ level
change will be detected and then take an ‘OR’ operation to generate the
INT1 or INT2 IRQ request.
If INT1 or INT2 IRQ request generates, the signal will be latched. User
should apply the function “_7396_CLR_IRQ” or “_7348_CLR_IRQ” to reset
its state, after the corresponding ISR is finished,

Operation Theorem • 29
4.4 12V and 5V Power Supply
The SCSI-100 connector CN1 provides +12V and +5V power supply (only
for PCI-7348) for external devices. To avoid the short circuit or the overload
of the power supply, the resettable fuses are added on all the power
supply signals.
The maximum current for 5V power supply is 0.5 A. If the load current is
larger than this limitation, the resistance of the resettable fuse will increase
for the reason of the rising temperature. The rising resistance will further
cause the power supply to reduce the load current. After the condition of
overload or short circuit is removed, the fuse will return to its normal
condition. It is unnecessary to replace the fuse.
The maximum current of 12V power supply is 0.5A, too. The action of the
fuse is the same as that of +5V power supply.

A2.5 Circuits and Wiring
The connection of isolated digital output is shown as the following diagram.
The DIN-96DO need external 5~24V DC power from the POWER pin to
provide the power source of the digital output circuit. The POWER pin is
used as “fly-wheel” diode, which can protect the driver if the loading is
inductance loading such as relay, motor or solenoid. If the loading is
resistance loading such as resistor or LED, the connection to fly-wheel diode
is not necessary.
Therefore, the first step for connecting the output with external device is to
distinguish the type of loading. For example, if the loading is LED or resistor,
you can use the following wiring diagram.
