Intel® IXF1104 4-Port Gigabit Ethernet Media Access Controller

8.3Per Port Registers

Section 8.4 covers all of the registers that are replicated in each port of the IXF1104 MAC. These registers perform an identical function in each port.

The address vector for the IXF1104 MAC is 11 bits wide. This allows for 7 bits of port-specific access and a 4-bit vector to address each port and all global registers. The address format is shown in Figure 54.
