bit 7 CRCERREN: CRC Error Collection Enable bit

1 = The received packet CRC must be invalid for the packet to be accepted

0 = Disable CRC Error Collection filtering

This bit allows the user to collect all packets that have an invalid CRC.

bit 6 CRCOKEN: CRC OK Enable bit

1 = The received packet CRC must be valid for the packet to be accepted

0 = Disable CRC filtering

This bit allows the user to reject all packets that have an invalid CRC.

bit 5 RUNTERREN: Runt Error Collection Enable bit

1 = The received packet must be a runt packet for the packet to be accepted

0 = Disable Runt Error Collection filtering

This bit allows the user to collect all packets that are runt packets. For this filter, a runt packet is defined as

any packet with a size of less than 64 bytes (when CRCOKEN = 0) or any packet with a size of less than

64 bytes that has a valid CRC (when CRCOKEN = 1).

bit 4 RUNTEN: Runt Enable bit

1 = The received packet must not be a runt packet for the packet to be accepted

0 = Disable Runt filtering

This bit allows the user to reject all runt packets. For this filter, a runt packet is defined as any packet with a

size of less than 64 bytes.

bit 3 UCEN: Unicast Enable bit

1 = Enable Unicast Filtering

0 = Disable Unicast Filtering

This bit allows the user to accept all unicast packets whose Destination Address matches the Station

Address.

bit 2 NOTMEEN: Not Me Unicast Enable bit

1 = Enable Not Me Unicast Filtering

0 = Disable Not Me Unicast Filtering

This bit allows the user to accept all unicast packets whose Destination Address does not match the Station

Address.

bit 1 MCEN: Multicast Enable bit

1 = Enable Multicast Filtering

0 = Disable Multicast Filtering

This bit allows the user to accept all Multicast Address packets.

bit 0 BCEN: Broadcast Enable bit

1 = Enable Broadcast Filtering

0 = Disable Broadcast Filtering

This bit allows the user to accept all Broadcast Address packets.

(CONTINUED)

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.
