3.0 PROGRAMMING INFORMATION

This Section provides the specific information necessary to program and
operate the AP48X module.

The PCIe bus is defined to address three distinct address spaces: I/O,
memory, and configuration space. The AcroPack module can be accessed
via the PCIe bus memory space and configuration spaces, only.

The AcroPack configuration registers are initialized by system software at
power-up to configure the card. The AcroPack module is a Plug-and-Play
PCIe card. As a Plug-and-Play card th

e board’s base address and system

interrupt request are not selected via jumpers but are assigned by system
software upon power-up via the configuration registers. A PCIe bus
configuration access is used to access the

AcroPack’s configuration registers.

When the computer is first powered-

up, the computer’s system

configuration software scans the PCIe bus to determine what PCIe devices
are present. The software also determines the configuration requirements
of the PCIe card.

The system software accesses the configuration registers to determine how
many blocks of memory space the module requires. It then programs the

board’s configuration registers with the unique memory base address.

Since this board is not fixed in address space, its device driver must use the

mapping information stored in the board’s Configuration Space registers to

determine where the board is mapped in memory space.

The configuration registers are also used to indicate that the board requires
an interrupt request. The system software then programs the configuration
registers with the interrupt request for the board.

URATION REGISTERS

The PCIe specification requires software driven initialization and
configuration via the Configuration Address space. This board provides 512
bytes of configuration registers for this purpose. It contains the
configuration registers shown in the following table to facilitate Plug-and-
Play compatibility.

The Configuration Registers are accessed via the Configuration Address and
Data Ports. The most important Configuration Registers are the Base
Address Registers and the Interrupt Register which must be read to
determine the base address assigned to the board and the interrupt request
that goes active on a board interrupt request.
