PCI Configuration Registers
The following is a list of those registers that would typi-
cally need to be programmed once during the initializa-
tion of the PCnet-PCI II controller within a system:
I
PCI I/O Base Address or Memory Mapped I/O Base
Address register
I
PCI Expansion ROM Base Address register

PCI Interrupt Line register

PCI Latency Timer register

PCI Status register

PCI Command register
Setup Registers
The following is a list of those registers that would typi-
cally need to be programmed once during the setup of
the PCnet-PCI II controller within a system. The control
bits in each of these registers typically do not need to be
modified once they have been written. However, there
are no restrictions as to how many times these registers
may actually be accessed. Note that if the default power
up values of any of these registers is acceptable to the
application, then such registers need never be ac-
cessed at all. Registers marked with “^” may be pro-
grammable through the EEPROM read operation, and
therefore do not necessarily need to be written to by the
system initialization procedure or by the driver software.
Registers marked with “*” will be initialized by the initiali-
zation block read operation.

Running Registers
The following is a list of those registers that would typi-

during the normal running operation of the PCnet-PCI II
controller within a system. Each of these registers con-
tains control bits or status bits or both.

PCI Status register
PCI Configuration Registers
PCI Vendor ID (Offset 00h)
The PCI Vendor ID register is a 16-bit register that iden-
tifies the manufacturer of the PCnet-PCI II controller.
Advanced Micro Devices, Inc.’s (AMD) 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.
Register Address Port
PCnet-PCI II Controller Status
Test and Features Control
Extended Control and Interrupt
Missed Frame Count
Receive Collision Count
The PCI Vendor ID register is located at offset 00h in the
PCI Configuration Space. It is read only.
PCI Device ID Register (Offset 02h)
The PCI Device ID register is a 16-bit register that
uniquely identifies the PCnet-PCI II controller within
AMD’s product line. The PCnet-PCI II controller Device
ID is 2000h. Note that this Device ID is not the same as
the Part number in CSR88 and CSR89. The Device ID is
assigned by Advanced Micro Devices, Inc.
