54 / 62 page  AMD 54 Am79C90 Table A-1 “Mapping of Logical Address to Filter Mask” can be used to find a multicast address that maps into a particular address filter bit. For example, address BB 00 00 00 00 00 maps into bit 15. Therefore, any node that has bit 15 set in its logical address filter register will re- ceive all packets addressed to BB 00 00 00 00 00. The table also shows that bit 15 is located in bit 7 of byte 1 of the Logical Address Filter Register. Addresses in this table are shown in the standard Ether- net format. The leftmost byte is the first byte to appear on the network with the least significant bit appearing first. Table A-1.
