Bits 23:16 Reserved
Bits 15:0 MACA3H: MAC address3 high [47:32]

Bit 30 SA: Source address
Ethernet MAC address 3 low register (ETH_MACA3LR)
Address offset: 0x005C
Reset value: 0xFFFF FFFF
The MAC address 3 low register holds the lower 32 bits of the 6-byte second MAC address
of the station.
When this bit is set, the address filters use the MAC address3 for perfect filtering. When this bit
is cleared, the address filters ignore the address for filtering.
When this bit is set, the MAC address 3 [47:0] is used for comparison with the SA fields of the
received frame.
When this bit is cleared, the MAC address 3[47:0] is used for comparison with the DA fields of
the received frame.
These bits are mask control bits for comparison of each of the MAC address3 bytes. When
these bits are set high, the MAC core does not compare the corresponding byte of received
DA/SA with the contents of the MAC address 3 registers. Each bit controls the masking of the
bytes as follows:
– Bit 29: ETH_MACA3HR [15:8]
– Bit 28: ETH_MACA3HR [7:0]
– Bit 27: ETH_MACA3LR [31:24]
…
– Bit 24: ETH_MACA3LR [7:0]
This field contains the upper 16 bits (47:32) of the 6-byte MAC address3.
This field contains the lower 32 bits of the 6-byte second MAC address3. The content of this
field is undefined until loaded by the application after the initialization process.
