Switch Port 0, Port 1, and Port 2 CSRs
This section details the switch Port 0(Host MAC), 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
register numbers is included in
Port x MAC Version ID Register (MAC_VER_ID_x)
This read-only register contains switch device ID information, including the device type, chip version
and revision codes.
