Bits 30:16 Reserved
Bits 15:0 MACA0H: MAC address0 high [47:32]
Bits 31:0 MACA0L: MAC address0 low [31:0]
Bit 31 MO: Always 1.
Ethernet MAC address 0 low register (ETH_MACA0LR)
Address offset: 0x0044
Reset value: 0xFFFF FFFF
The MAC address 0 low register holds the lower 32 bits of the 6-byte first MAC address of
the station.
Ethernet MAC address 1 high register (ETH_MACA1HR)
Address offset: 0x0048
Reset value: 0x0000 FFFF
The MAC address 1 high register holds the upper 16 bits of the 6-byte second MAC address
of the station.
Bit 31 AE: Address enable
Bit 30 SA: Source address
MBC
This field contains the upper 16 bits (47:32) of the 6-byte MAC address0. This is used by the
MAC for filtering for received frames and for inserting the MAC address in the transmit flow
control (Pause) frames.
This field contains the lower 32 bits of the 6-byte MAC address0. This is used by the MAC for
filtering for received frames and for inserting the MAC address in the transmit flow control
(Pause) frames.
When this bit is set, the address filters use the MAC address1 for perfect filtering. When this bit
is cleared, the address filters ignore the address for filtering.
When this bit is set, the MAC address1[47:0] is used for comparison with the SA fields of the
received frame.
When this bit is cleared, the MAC address1[47:0] is used for comparison with the DA fields of
the received frame.
