9.2 CRC4 ERROR COUNTER
CRC4 Count Register 1 (CRCCR1) is the most significant word and CRCCR2 is the least significant word of a
16–bit counter that records word errors in the Cyclic Redundancy Check 4 (CRC4). Since the maximum CRC4
count in a one second period is 1000, this counter cannot saturate. The counter is disabled during loss of sync at
either the FAS or CRC4 level; it will continue to count if loss of multiframe sync occurs at the CAS level.
CRCCR1 and CRCCR2 have an alternate function.
