Host MAC Control and Status Registers

This section details the Host MAC System CSR’s. These registers are located in the Host MAC and

are accessed indirectly via the HBI system CSR’s. Table 14.6 lists Host MAC registers that are

accessible through the indexing method using the Host MAC CSR Interface Command Register

(MAC_CSR_CMD) and Host MAC CSR Interface Data Register (MAC_CSR_DATA).

The Host MAC registers allow configuration of the various Host MAC parameters including the Host

MAC address, flow control, multicast hash table, and wake-up configuration. The Host MAC CSR’s

also provide serial access to the PHYs via the registers HMAC_MII_ACC and HMAC_MII_DATA.

These registers allow access to the 10/100 Ethernet PHY registers and the switch engine (via Port 0).
