6.3.4.3 Specific Address 1 Bottom (SPECAD1BOT)
This register contains the least-significant bits (bits [31:0]) of the destination address.
Bit zero indicates whether the address is multicast or unicast and corresponds to the least
significant bit of the first byte received
. SPECAD1 should be programmed with the system
MAC address.
6.3.4.4 Specific Address 1 Top (SPECAD1TOP)
This register contains the most-significant bits of the destination address (bits [47:32]).
