MCAST_ADDR_0 (offset = 0x48)
This register combined with MCAST_ADDR_1 (offset = 0x4C) provides 64-bit field to qualify
multicast frame destined to this Ethernet MAC. Only one bit out of 64-bits should be set to
determine valid multicast address. The bit position to be set is calculated by applying CRC over
destination address field of incoming multicast frame.
