RO
TXMA Transmit Memory Available
The amount of memory available is represented in units of byte. The TXQ memory is
used for both frame payload, control word.
Note: Software must be written to ensure that there is enough memory for the next
transmit frame including control information before transmit data is written to the TXQ.
0x7A – 0x7B: Reserved
Receive Frame Header Status Register (0x7C – 0x7D): RXFHSR
This register indicates the received frame header status information, the received frames are reported in RXFCTR
register. This register contains the status information for the frame received and the CPU can read so many times same
as the frame count value in the RXFCTR.
Bit
Default Value
R/W
Description

RO
RXFV Receive Frame Valid
When this bit is set, it indicates that the present frame in the receive packet memory is
valid. The status information currently in this location is also valid.
When clear, it indicates that there is either no pending receive frame or that the current
frame is still in the process of receiving.

RO
RXICMPFCS Receive ICMP Frame Checksum Status
When this bit is set, the KSZ8851 received ICMP frame checksum field is incorrect.
12
-
RO
RXIPFCS Receive IP Frame Checksum Status
When this bit is set, the KSZ8851 received IP header checksum field is incorrect.
11
-
RO
RXTCPFCS Receive TCP Frame Checksum Status
When this bit is set, the KSZ8851 received TCP frame checksum field is incorrect.

RO
RXBF Receive Broadcast Frame
When this bit is set, it indicates that this frame has a broadcast address.
6
-
RO
RXMF Receive Multicast Frame
When this bit is set, it indicates that this frame has a multicast address (including the
broadcast address).
5
-
RO
RXUF Receive Unicast Frame
When this bit is set, it indicates that this frame has a unicast address.
4

RO
RXMR Receive MII Error
When set, it indicates that there is an MII symbol error on the received frame.
3
-
RO
RXFT Receive Frame Type
When this bit is set, it indicates that the frame is an Ethernet-type frame (frame length is
greater than 1500 bytes). When clear, it indicates that the frame is an IEEE 802.3 frame.
This bit is not valid for runt frames.
