bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7 UCEN: Unicast Filter Enable bit
When ANDOR = 1:
1 = Packets not having a destination address matching the local MAC address will be discarded
0 = Filter disabled
When ANDOR = 0:
1 = Packets with a destination address matching the local MAC address will be accepted
0 = Filter disabled
bit 6 ANDOR: AND/OR Filter Select bit
1 = AND: Packets will be rejected unless all enabled filters accept the packet
0 = OR: Packets will be accepted unless all enabled filters reject the packet
bit 5 CRCEN: Post-Filter CRC Check Enable bit
1 = All packets with an invalid CRC will be discarded
0 = The CRC validity will be ignored
bit 4 PMEN: Pattern Match Filter Enable bit
When ANDOR =
1:
1 = Packets must meet the Pattern Match criteria or they will be discarded
0 = Filter disabled
When ANDOR = 0:
1 = Packets which meet the Pattern Match criteria will be accepted
0 = Filter disabled
bit 3 MPEN: Magic Packet™ Filter Enable bit
When ANDOR =
1:
1 = Packets must be Magic Packets for the local MAC address or they will be discarded
0 = Filter disabled
When ANDOR = 0:
1 = Magic Packets for the local MAC address will be accepted
0 = Filter disabled
bit 2 HTEN: Hash Table Filter Enable bit
When ANDOR =
1:
1 = Packets must meet the Hash Table criteria or they will be discarded
0 = Filter disabled
When ANDOR = 0:
1 = Packets which meet the Hash Table criteria will be accepted
0 = Filter disabled
bit 1 MCEN: Multicast Filter Enable bit
When ANDOR =
1:
1 = Packets must have the Least Significant bit set in the destination address or they will be discarded
0 = Filter disabled
When ANDOR =
0:
1 = Packets which have the Least Significant bit set in the destination address will be accepted
0 = Filter disabled
bit 0 BCEN: Broadcast Filter Enable bit
When ANDOR =
1:
1 = Packets must have a destination address of FF-FF-FF-FF-FF-FF or they will be discarded
0 = Filter disabled
When ANDOR = 0:
1 = Packets which have a destination address of FF-FF-FF-FF-FF-FF will be accepted
0 = Filter disabled
