Address Matching
Ethernet addresses consist of two 6-byte fields. The first
bit of the address signifies whether it is a Station Address
or a Multicast/Broadcast Address.

Multicast Address:
If the first bit of the incoming address
is a 1 and the EDLC chip is programmed to accept
Multicast Addresses without using Hash filtering, the
frame s received. The 80C03 also can be programmed to
use hash filter for determining acceptance of multicast
addresses.

(logical)
Address matching occurs as follows:
Station Address:
All destination address bytes must
match the corresponding bytes found in the Station Ad-
dress Register. If Group Address mode s enabled, he ast
4 bits of he station address are masked out during address
matching.
After computing the FCS on the first six bytes of the
address field (Destination address), the 80C03 uses bits 0
thru 5 as an address to the Multi-cast address filter
register. Bit 0 of the FCS is assumed to be where receive
data enters the FCS generation circuitry. If the corre-
sponding bit addressed in the Multicast address filter
register s a 1’ the 80C03 will receive the frame, otherwise
it will discard the frame. Addressing of the Multicast
address filter register occurs using bits 0 thru 2 to deter-
