31.3.10.22 CRC Bits in INTFLAG

For manual CRC, the CRCDONE bit indicates that the operation is complete with all bits in the message acted upon. The CRCERR bit may or may not be set. For auto repeat CRC, the CRCDONE bit is only set when there is an error so CRCERR is also set. This condition also causes the looping to stop.

The CRCERR bit reports the status of the compare at the end of the CRC when all bits in the message finish shifting into the LFSR.

CRCERR = ![CRCSUM = (CRCACC xor CRCFXOR)]
