R/W
MAC Address 1 low bit [31:0]
This bit field contains the low 32 bits of the first 6-byte MAC address
1. If the application does not load the content of this bit field after
initialization, the content will not be defined.

29:24 MASKBCTRL
R/W
Mask Byte Control
These bits are used to compare the mask control bits of 2 bytes of
each MAC address. When they are set to high level, the MAC core
will not compare the corresponding bytes of the received DA/SA
with the contents of the MAC address 2 register. Each bit is used to
control the mask of bytes, as follows:
Bit 29: ADDR2H [15:8]
Bit 28: ADDR2H [7:0]
Bit 27: ADDR2L [31:24]
