MAC Control and Status Registers
These registers are located in the MAC module and are accessed indirectly through the MAC-CSR
synchronizer port. Table 5.6, "MAC CSR Register Map", shown below, lists the MAC registers that are
accessible through the indexing method using the MAC_CSR_CMD and MAC_CSR_DATA registers
(see sections MAC_CSR_CMD – MAC CSR Synchronizer Command Register and MAC_CSR_DATA
– MAC CSR Synchronizer Data Register).
