Preliminary Specification

The PCI datapath block contains the multiplexors and registers to steer the data to and from the PCI interfaces. The
data is de-multiplexed from the external PCI interface to the internal master and slave busses. Control logic from the
master and slave devices control the datapath.
The SSA7785 ThunderBird Avenger is considered a multi-function device since the operating system may wish to
load different drivers for certain functions. These functions are the audio subsystem, the joystick and the 16650 UART.
Each of these major functions must have a separate PCI configuration space. The standard PCI configuration header
for these three functions are supported in the PCI interface.
The SSA7785 ThunderBird Avenger PCI interface responds to and initiates PCI cycles with positive decoding
according to the PCI 2.1 specification. The interface asserts DEVSEL# after the first clock following FRAME# making it
a medium responder. For specific LAM cycles, the SSA7785 ThunderBird Avenger will be a fast responder. SSA7785
ThunderBird Avenger indicates which cycles the PCI interface responds to or initiates.
TABLE 5
PCI Bus Command Definitions and
SSA7785 ThunderBird Avenger
Responses
The SSA7785 ThunderBird Avenger will respond to byte, word, tri-byte or double word access for configuration read
and configuration write cycles provided PCI addressing rules are followed. Byte and word width accesses allowed for
I/O cycles depend largely on the target I/O device. In general, 24-bit and 32-bit accesses are not allowed to I/O devices
and will result in a target abort. The SSA7785 ThunderBird Avenger performs double word accesses when initiating
