For any valid, non-zero MAC address received, exact match registers can be excluded individually by
clearing them to all zero bytes.
Table 16-53 describes the fields of a MACnADDR1 register.
16.5.3.5.16 MAC Exact Match Address 1–15 Part 2 Registers
(MAC01ADDR2–MAC15ADDR2)
The MAC01ADDR2–MAC15ADDR2 registers are written by the user with the unicast or multicast
addresses aliasing the MAC. Figure 16-50 describes the definition for all of the fifteen MACxADDR2
registers.

Table 16-53. MACnADDR1 Field Descriptions
Bit Name Description
0–7 Exact Match Address, 6th Octet Holds the sixth octet of the exact match address. The sixth octet (destination
address bits 40
47) defaults to a value of 0x0.
8–15 Exact Match Address, 5th Octet Holds the fifth octet of the exact match address. The fifth octet (destination
address bits 3239) defaults to a value of 0x0.
16–23 Exact Match Address, 4th Octet Holds the fourth octet of the exact match address. The fourth octet (destination
address bits 2431) defaults to a value of 0x0.
24–31 Exact Match Address, 3rd Octet Holds the third octet of the exact match address. The third octet (destination
address bits 16
23) defaults to a value of 0x0.
