AX88796 L 3-in-1 Local Bus Fast Ethernet Controller
If address Y is found to hash to the value 32 (20H), then FB32 in MAR2 should be initialized to ``1''. This will cause the
AX88796 to accept any multicast packet with the address Y.
Although the hashing algorithm does not guarantee perfect filtering of multicast address, it will perfectly filter up to 64
logical address filteres if these addresses are chosen to map into unique locations in the multicast filter.
Note:
The first bit of received packet sequence is 1’s stands by Multicast Address.
4.1.3 Broadcast Address Match Filter
The Broadcast check logic compares the Destination Address Field (first 6 bytes of the received packet) to all 1’s, that is
the values are “FF FF FF FF FF FF FF” in Hex format. If any bit of the six bytes does not equal to 1’s, the Protocol Control
Logic rejects the packet.
4.1.4 Aggregate Address Filter with Receive Configuration Setup
The final address filter decision depands on the destination address types, identified by the above 3 address
match filters, and the setup of parameters of Receive Configuration Register.
Definitions of address match filter result are as following:
Signal
