Figure 13. PCI Configuration Registers
Configuration Registers
The 82551IT acts as both a master and a slave on the PCI bus. As a master, the 82551IT interacts
with the system main memory to access data for transmission or deposit received data. As a slave,
some 82551IT control structures are accessed by the host CPU to read or write information to the
on-chip registers. The CPU also provides the 82551IT with the necessary commands and pointers
that allow it to process receive and transmit data.
Function 0: LAN (Ethernet) PCI Configuration Space
The 82551IT 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
