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.
accessible through the indexing method using the
(MAC_CSR_CMD)
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).
