gmacgrp_mac_address36_high 

          Register 552 (MAC Address36 High Register)   

The MAC Address36 High register holds the upper 16 bits of the 37th 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) or Bits[7:0] (in big-endian mode) of the MAC Address36 Low Register are written. For proper synchronization updates, consecutive writes to this MAC Address36 Low Register must be performed after at least four clock cycles in the destination clock domain.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

When this bit is set, the address filter module uses the 37th MAC address for perfect filtering. 
When this bit is reset, the address filter module ignores the address for filtering.
