Bit 2: CRC Resync Criteria Met Event (CRCRC). Set when 915/1000 codewords are received in error.
Bit 1: FAS Resync Criteria Met Event (FASRC). Set when three consecutive FAS words are received in error.
Note: During a CRC resync the FAS synchronizer is brought online to verify the FAS alignment. If during this
process an FAS emulator exists, the FAS synchronizer may temporarily align to the emulator. The FASRC will go
active indicating a search for a valid FAS has been activated.
Bit 0: CAS Resync Criteria Met Event (CASRC). Set when two consecutive CAS MF alignment words are
received in error.
