These registers are intended to be used by the device
driver software after the Am79C973/Am79C975 con-
troller is running to access status information and to
pass control information.
The following is a list of the registers that would typi-
cally need to be periodically read and perhaps written
during the normal running operation of the Am79C973/
Am79C975 controller within a system. Each of these
registers contains control bits, or status bits, or both.

These registers are intended to be used only for testing
and diagnostic purposes. Those registers not included
in any of the above lists can be assumed to be intended
for diagnostic purposes.
PCI Configuration Registers
PCI Vendor ID Register
Offset 00h
The PCI Vendor ID register is a 16-bit register that iden-
tifies the manufacturer of the Am79C973/Am79C975
controller. AMD’s Vendor ID is 1022h. Note that this
vendor ID is not the same as the Manufacturer ID in
CSR88 and CSR89. The vendor ID is assigned by the
PCI Special Interest Group.
The PCI Vendor ID register is located at offset 00h in
the PCI Configuration Space. It is read only.
This register is the same as BCR35 and can be written
by the EEPROM.
PCI Device ID Register
Offset 02h
The PCI Device ID register is a 16-bit register that
uniquely identifies the Am79C973/Am79C975 control-
