Bits 23:16Reserved
Bits 15:0
Bits 31:0
Ethernet MAC address 2 low register (ETH_MACA2LR)
Address offset: 0x0054
Reset value: 0xFFFF FFFF
The MAC address 2 low register holds the lower 32 bits of the 6-byte second MAC address
of the station.
Ethernet MAC address 3 high register (ETH_MACA3HR)
Address offset: 0x0058
Reset value: 0x0000 FFFF
The MAC address 3 high register holds the upper 16 bits of the 6-byte second MAC address
of the station.
Bit 30
MBC
SA: Source address
When this bit is set, the MAC address 2 [47:0] is used for comparison with the SA fields of the
received frame.
When this bit is reset, the MAC address 2 [47:0] is used for comparison with the DA fields of
the received frame.
MBC: Mask byte control
These bits are mask control bits for comparison of each of the MAC address2 bytes. When set
high, the MAC core does not compare the corresponding byte of received DA/SA with the
contents of the MAC address 2 registers. Each bit controls the masking of the bytes as follows:
– Bit 29: ETH_MACA2HR [15:8]
– Bit 28: ETH_MACA2HR [7:0]
– Bit 27: ETH_MACA2LR [31:24]
…
– Bit 24: ETH_MACA2LR [7:0]
MACA2H: MAC address2 high [47:32]
This field contains the upper 16 bits (47:32) of the 6-byte MAC address2.
MACA2L: MAC address2 low [31:0]
This field contains the lower 32 bits of the 6-byte second MAC address2. The content of this
field is undefined until loaded by the application after the initialization process.
