6.3.4.9 Specific Address 4 Bottom (SPECAD4BOT)
This register contains the least-significant bits of the destination address (bits [31:0]). Bit
zero indicates whether the address is multicast or unicast and corresponds to the least
significant bit of the first byte received
.
6.3.4.10 Specific Address 4 Top (SPECAD4TOP)
This register contains the most-significant bits of the destination address (bits [47:32]).
