Bit field Name Description
31 AE Address enable.
0: Address filter does not use MAC address 2 for perfect filtering.
1: Address filter uses MAC address 2 for perfect filtering.
30 SA Source address comparison.
0: MAC address 2 is used to compare with the destination address of the received
frame.
1: MAC address 2 is used to compare with the source address of the received frame.
29:24 MBC[5:0] Mask byte control bits.
When a bit is set to 1, MAC will ignore the comparison of the corresponding byte of
the destination/source address of the received frame with the corresponding byte of
the MAC address 2. The MAC address bytes corresponding to each control bit are as
follows:
MBC[5]: ETH_MACADDR2HI[15:8]
MBC[4]: ETH_MACADDR2HI[7:0]
MBC[3]: ETH_MACADDR2LO[31:24]
MBC[2]: ETH_MACADDR2LO[23:16]
MBC[1]: ETH_MACADDR2LO[15:8]
MBC[0]: ETH_MACADDR2LO[7:0]
23:16 Reserved Reserved, the reset value must be maintained.
15:0 ADDRHI[15:0] MAC address 2 high 16 bits.
These bits contain the upper 16 bits of the 6-byte MAC address 2.
25.5.19 ETH MAC address 2 low register (ETH_MACADDR2LO)
Address offset: 0x0054
Reset value: 0xFFFF FFFF
Bit field Name Description
31:0 ADDRLO[31:0] MAC address 2 low 32 bits.
These bits contain the lower 32 bits of the 6-byte MAC address 2.
25.5.20 ETH MAC address 3 high register (ETH_MACADDR3HI)
Address offset: 0x0058
Reset value: 0x0000 FFFF
