Switch Port 0, Port 1, and Port 2 CSRs

This section details the switch Port 0(External MII), Port 1, and Port 2 CSRs. Each port provides a

functionally identical set of registers which allow for the configuration of port settings, interrupts, and

the monitoring of the various packet counters.

Because the Port 0, Port 1, and Port 2 CSRs are functionally identical, their register descriptions have

been consolidated. A lowercase “x” has been appended to the end of each switch port register name

in this section, where “x” should be replaced with “MII”, “1”, or “2” for the Port 0, Port 1, or Port 2

registers respectively. A list of the Switch Port 0, Port 1, and Port 2 registers and their corresponding
