PCI Configuration Registers
The 82559ER acts as both a master and a slave on the PCI bus. As a master, the 82559ER interacts
with the system main memory to access data for transmission or deposit received data. As a slave,
some 82559ER control structures are accessed by the host CPU to read or write information to the
on-chip registers. The CPU also provides the 82559ER with the necessary commands and pointers
that allow it to process receive and transmit data.
LAN (Ethernet) PCI Configuration Space
The 82559ER PCI configuration space is configured as 16 Dwords of Type 0 Configuration Space
Header, as defined in the PCI Specification, Revision 2.1. A small section is also configured
according to its device specific configuration space. The configuration space header is depicted
below in
