Bits 29:24 MBC: Mask byte control
Bits 23:16 Reserved
Bits 15:0 MACA1H: MAC address1 high [47:32]
Bits 31:0 MACA1L: MAC address1 low [31:0]
Ethernet MAC address1 low register (ETH_MACA1LR)
Address offset: 0x004C
Reset value: 0xFFFF FFFF
The MAC address 1 low register holds the lower 32 bits of the 6-byte second MAC address
of the station.
Ethernet MAC address 2 high register (ETH_MACA2HR)
Address offset: 0x0050
Reset value: 0x0000 FFFF
The MAC address 2 high register holds the upper 16 bits of the 6-byte second MAC address
of the station.
Bit 31
MBC
AE: Address enable
When this bit is set, the address filters use the MAC address2 for perfect filtering. When reset,
the address filters ignore the address for filtering.
These bits are mask control bits for comparison of each of the MAC address1 bytes. When
they are set high, the MAC core does not compare the corresponding byte of received DA/SA
with the contents of the MAC address1 registers. Each bit controls the masking of the bytes as
follows:
– Bit 29: ETH_MACA1HR [15:8]
– Bit 28: ETH_MACA1HR [7:0]
– Bit 27: ETH_MACA1LR [31:24]
…
– Bit 24: ETH_MACA1LR [7:0]
This field contains the upper 16 bits (47:32) of the 6-byte second MAC address.
This field contains the lower 32 bits of the 6-byte MAC address1. The content of this field is
undefined until loaded by the application after the initialization process.
