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 31-16 Unimplemented: Read as ‘0’
bit 15 HTEN: Enable Hash Table Filtering bit
1 = Enable Hash Table Filtering
0 = Disable Hash Table Filtering
bit 14 MPEN: Magic Packet™ Enable bit
1 = Enable Magic Packet Filtering
0 = Disable Magic Packet Filtering
bit 13 Unimplemented: Read as ‘0’
bit 12 NOTPM: Pattern Match Inversion bit
1 = The Pattern Match Checksum must not match for a successful Pattern Match to occur
0 = The Pattern Match Checksum must match for a successful Pattern Match to occur
This bit determines whether Pattern Match Checksum must match in order for a successful Pattern Match
to occur.

1001 = Pattern match is successful if (NOTPM = 1 XOR Pattern Match Checksum matches) AND

(Hash Table Filter match)

0001 = Pattern match is successful if (NOTPM = 1 XOR Pattern Match Checksum matches)
(1)
0000 = Pattern Match is disabled; pattern match is always unsuccessful
Note 1: XOR = True when either one or the other conditions are true, but not both.
2: This Hash Table Filter match is active regardless of the value of the HTEN bit.
3: This Magic Packet Filter match is active regardless of the value of the MPEN bit.
Note 1: This register is only used for RX operations.
2: The bits in this register may only be changed while the RXEN bit (ETHCON1<8>) = 0.
