5.4 FAS Error Counter
FAS Count Register 1 (FASCR1) is the most significant word and FASCR2 is the least significant word
of a 12-bit counter that records word errors in the Frame Alignment Signal in timeslot 0. This counter is
disabled during loss of synchronization conditions, (RLOS = 1). Since the maximum FAS word error
count in a 1-second period is 4000, this counter cannot saturate.

NAME AND DESCRIPTION
FAS11
FASCR1.7
MSB of the 12-bit FAS error count.
FAS0
FASCR2.2
LSB of the 12-bit FAS error count.
NOTES:
1.
The lower 2 bits of FASCR1 at address 02 are the most significant bits of the 10-bit CRC4 error
counter.
2.
The lower 2 bits of FASCR2 at address 04 are the most significant bits of the 10-bit E-bit counter.
