RW
RXBE Receive Broadcast Enable
When this bit is set, the RX module receives all the broadcast frames.
6
0x0
RW
RXME Receive Multicast Enable
When this bit is set, the RX module receives all the multicast frames (including broadcast
frames).
5
0x0
RW
RXUE Receive Unicast Enable
When this bit is set, the RX module receives unicast frames that match the 48-bit Station
MAC address of the module.
4
0x0
RW
RXAE Receive All Enable
When this bit is set, the KSZ8851-16MLLJ receives all incoming frames, regardless of the
frame’s destination address (see Address Filtering Scheme in Table 3 for detail).

RXINVF Receive Inverse Filtering
When this bit is set, the KSZ8851-16MLLJ receives function with address check operation
in inverse filtering mode (see Address Filtering Scheme in Table 3 for detail).
0
0x0
RW
RXE Receive Enable
When this bit is set, the RX block is enabled and placed in a running state.
When this bit is cleared, the receive process is placed in the stopped state upon
completing reception of the current frame.
Receive Control Register 2 (0x76 – 0x77): RXCR2
This register holds control information programmed by the CPU to control the receive function.

RW
IUFFP IPV4/IPV6/UDP Fragment Frame Pass
When this bit is set, the KSZ8851-16MLLJ will pass the checksum check at receive side
for IPv4/IPv6 UDP frame with fragment extension header.
When this bit is cleared, the KSZ8851-16MLLJ will perform checksum operation based on
configuration and doesn’t care whether it’s a fragment frame or not.
3
0x0
RW
RXIUFCEZ Receive IPV4/IPV6/UDP Frame Checksum Equal Zero
When this bit is set, the KSZ8851-16MLLJ will pass the filtering for IPv4/IPv6 UDP frame
with UDP checksum equal to zero.
When this bit is cleared, the KSZ8851-16MLLJ will drop IPv4/IPv6 UDP packet with UDP
checksum equal to zero.
2
0x1
RW
UDPLFE UDP Lite Frame Enable
When this bit is set, the KSZ8851-16MLLJ will check the checksum at receive side and
generate the checksum at transmit side for UDP Lite frame.
When this bit is cleared, the KSZ8851-16MLLJ will pass the checksum check at receive
side and skip the checksum generation at transmit side for UDP Lite frame.
1
0x0
RW
RXICMPFCC Receive ICMP Frame Checksum Check Enable
When this bit is set, the KSZ8851 will check for correct ICMP checksum for incoming
ICMP frames (only for non-fragment frame). Any received ICMP frames with incorrect
checksum will be discarded.
0
0x0
RW
RXSAF Receive Source Address Filtering
When this bit is set, the KSZ8851-16MLLJ will drop the frame if the source address is
same as MAC address in MARL, MARM, MARH registers.
