15.5.3.5.15 MAC Exact Match Address 1–15 Part 1 Registers
The MAC01ADDR1–MAC15ADDR1 registers are written by the user with the unicast or multicast
addresses aliasing the MAC.
registers. The value of the address written into MACxADDR1 and MACnADDR2 is byte reversed from
how it would appear in the DA field of a frame in memory. For example, for a MAC address of
0x12345678ABCD, MACnADDR1 is set to 0xCDAB7856 and MACnADDR2 is set to 0x34120000. For
any valid, non-zero MAC address received, exact match registers can be excluded individually by clearing
them to all zero bytes.
