DS33Z11 Ethernet Mapper
The MAC circuitry generates a frame status for every frame that is received. This real time status can be read by
SU.RFSB0 to SU.RFSB3. Note the frame status is the “real time” status and hence the value will change as new
frames are received. Hence the real time status reflects the status in time and may not correspond to the current
received frame being processed. This is also true for the transmitted frames.

Frames with errors are usually rejected by the DS33Z11. The user has the option of accepting frames by settings
in Receive Frame Rejection Control register (SU.RFRC). The user can program whether to reject or accept
frames with the following errors:
MII error asserted during the reception of the frame
Dribbling bits occurred in the frame
CRC error occurred
Length error occurred—the length indicated by the frame length is inconsistent with the number of bytes
received
Control frame was received. The mode must be full duplex
Unsupported control frame was received
Note that frames received that are runt frames or frames with collision will automatically be rejected. In Hardware
Mode any frame received with errors is rejected and any frame transmitted with an error is retransmitted

Register
Comment
SU.TFRC
This register determines if the current frame is retransmitted due to various
transmit errors
SU.TFSL
and
SU.TFSH
These 2 registers provide the real time status of the transmit frame. Only apply
to the last frame transmitted.
SU.RFSB0
to 3
These registers provide the real time status for the received frame. Only apply
to the last frame received.
SU.RFRC
This register provides settings for reception or rejection of frame based on
errors detected by the MAC.
SU.RMFSRH
and
SU.RMFSRL
The settings for this register provide the maximum size of frames to be
accepted from the MII/RMII receive interface.
SU.MACCR
This register provides configuration control for the MAC
