Register 14: Ethernet MAC Address 0 High (EMACADDR0H), offset 0x040
The Ethernet MAC Address 0 High (EMACADDR0H) register holds the upper 16 bits of the first
6-byte MAC address of the station. The first (Destination Address) DA byte that is received on the
MII interface corresponds to the least significant byte (Bits [7:0]) of the MAC Address 0 Low Register
(EMACADDR0L) register. For example, if 0x112233445566 is received (0x11 in lane 0 of the first
column) on the MII as the destination address, then the EMAC Address 0 (EMACADDR0x) register
[47:0] is compared with 0x665544332211.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

MAC Address0 [47:32]
This field contains the upper 16 bits (47:32) of the first 6-byte MAC
address. The MAC uses this field for filtering the received frames and
inserting the MAC address in the Transmit Flow Control (PAUSE)
Frames.
