Running Registers
These registers are intended to be used by the device
driver software after the Am79C978 controller is run-
ning 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 Am79C978
controller within a system. Each of these registers con-
tains control bits, or status bits, or both.

Test Registers
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 Am79C978 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
helps identify the Am79C978 controller within AMD's
product line. The Am79C978 Device ID is 2001h. Note
that this Device ID is not the same as the part number
in CSR88 and CSR89. The Device ID is assigned by
