USB-2.0 to Ethernet
MAC Address Registers
HIF_REG16 to HIF_REG21:
The Ethernet MAC Address (Station Address) is 46 bits + 2 bits indicating multi-cast/uni-cast, and local/global.
Six HIF Registers (HIF_REG16 to HIF_REG21) are used to store the Ethernet MAC Station Address.
Byte-1:
The two least signifi cant bits indicate whether the address is a uni-cast or multi-cast address, and also
whether it is a Local or Global address.
Bit-0:
0 = uni-cast address.
1 = multi-cast address.
Bit-1:
0 = global address.
1 = local address.
The most signifi cant bits (bit-2 to bit-7) of Byte-1, and all bits of the other Bytes (total of 46 bits) comprise the
station address.
