Number of received frames discarded because the RX buffer was
8 nRxBufFull R/W
full

23.5.1.4 Other Structures and Bit Fields
Table 23-67. Receive Queue Entry Configuration Bit Field
Bits Bit Field Name Description
0 bAutoFlushCrc If 1, automatically remove packets with CRC error from RX queue
If 1, automatically remove packets that can be ignored according to
1 bAutoFlushIgn
frame filtering from RX queue
If 1, include the received PHY header field in the stored packet;
2 bIncludePhyHdr
otherwise discard it
If 1, include the received CRC field in the stored packet; otherwise
3 bIncludeCrc
discard it
4 bAppendRssi If 1, append an RSSI byte to the packet in the RX queue
If 1, append a correlation value and CRC result byte to the packet in
5 bAppendCorrCrc
the RX queue
6 bAppendSrcInd If 1, append an index from the source matching algorithm
7 bAppendTimestamp If 1, append a timestamp to the packet in the RX queue
Table 23-68. CCA Configuration Bit Field
Bits Bit Field Name Description
0 ccaEnEnergy Enable energy scan as CCA source
1 ccaEnCorr Enable correlator based carrier sense as CCA source
2 ccaEnSync Enable sync found based carrier sense as CCA source
Operator to use between energy based and correlator based CCA
3 ccaCorrOp 0: Report busy channel if either ccaEnergy or ccaCorr are busy
1: Report busy channel if both ccaEnergy and ccaCorr are busy
Operator to use between sync found based CCA and the others
4 ccaSyncOp 0: Always report busy channel if ccaSync is busy
1: Always report idle channel if ccaSync is idle
Threshold for number of correlation peaks in correlator based carrier
5–6 ccaCorrThr
sense
7 Reserved
Table 23-69. Frame Filtering Configuration Bit Field
Bits Bit Field Name Description
0 frameFiltEn 0: Disable frame filtering. 1: Enable frame filtering
0: Receive all packets to the end. 1: Stop receiving frame
1 frameFiltStop
once frame filtering has caused the frame to be rejected.
2 autoAckEn 0: Disable auto ACK. 1: Enable auto ACK.
3 slottedAckEn 0: Nonslotted ACK. 1: Slotted ACK.
