High Performance Two Port 10/100 Managed Ethernet Switch with 32-Bit Non-PCI CPU Interface  
Datasheet  
14.5.2  
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 Table 14.12.
