11.6 Ethernet Interface Registers
The Ethernet Interface registers are used to configure RMII/MII bus operation and establish the MAC parameters
as required by the user. The MAC Registers cannot be addressed directly from the Processor port. The registers
below are used to perform indirect read or write operations to the MAC registers. The MAC Status Registers are
shown in
