5.2 Receive Descriptors
The receive descriptor provides one buffer, one byte-count buffer, and one address pointer in
each descriptor. Descriptors and receive buffers addresses must be long-word aligned.

5.2.1 Receive Descriptor 0 (RDES0)
RDES0 contains the received frame status, the frame length, and the descriptor ownership
information.
Field
31
Description
1
Indicates that the descriptor is owned by the AX88141
OWN - Own Bit
The AX88141 clears this bit either when it completes the
frame reception or
when the buffers that are associated with this descriptor are
full.
FF - Filtering Fail
This bit can be set only when receive all (REG6<30>) is set.
0
Indicates that the descriptor is owned by the host
1
0
Indicates that the frame failed the address recognition filtering
Indicates that the frame passed the address recognition filtering
30
29:16
FL - Frame Length
Indicates the length in bytes of the received frame including the cyclic redundancy check (CRC).
This field is valid only when last descriptor (RDES0<8>) is set and descriptor error ( RDES0<14>) is reset.
ES - Error Summary
Indicates the logical OR of the following RDES0 bits :
This field is valid only when last descriptor (RDES0<8>) is set.
RDES0<1>
CRC error
RDES0<6>
collision seen
RDES0<7>
frame too long
RDES0<11>
runt frame
RDES0<14>
descriptor error
15
14
DE - Descriptor Error. The frame is truncated. Active high.
This field is valid only when last descriptor (RDES0<8>) is set.
13:12
Reserved.--Written as “0” for future compatibility concern.
11
RF - Runt Frame. Indicates that this frame is a runt frame. Active high.
This field is valid only when last descriptor (RDES0<8>) is set .
