Register 692 (MAC Address106 High Register)
The MAC Address106 High register holds the upper 16 bits of the 107th 6-byte MAC address of the station.
If the MAC address registers are configured to be double-synchronized to the (G)MII clock domains, then
the synchronization is triggered only when Bits[31:24] (in little-endian mode) of the MAC Address106 Low Register are written. For proper synchronization updates, consecutive writes to this MAC Address106 Low Register must be performed after at least four clock cycles in the destination clock domain.
