Bit # 7 6 5 4 3 2 1 0
Name — BBED BBCO BEC0 BRA1 BRA0 BRLOS BSYNC
Default 0 0 0 0 0 0 0 0
Bit 0/BERT in Synchronization Condition (BSYNC)
0 = interrupt masked
1 = interrupt enabled—interrupts on rising and falling edges
Bit 1/Receive Loss-of-Synchronization Condition (BRLOS)
0 = interrupt masked
1 = interrupt enabled—interrupts on rising and falling edges
Bit 2/Receive All-Zeros Condition (BRA0)
0 = interrupt masked
1 = interrupt enabled—interrupts on rising and falling edges
Bit 3/Receive All-Ones Condition (BRA1)
0 = interrupt masked
1 = interrupt enabled—interrupts on rising and falling edges
Bit 4/BERT Error-Counter Overflow Event (BECO)
0 = interrupt masked
1 = interrupt enabled
Bit 5/BERT Bit-Counter Overflow Event (BBCO)
0 = interrupt masked
1 = interrupt enabled
Bit 6/Bit-Error Detected Event (BBED)
0 = interrupt masked
1 = interrupt enabled
BERT Alternating Word-Count Rate. When the BERT is programmed in the alternating word mode, the words
repeat for the count loaded into this register then flip to the other word and again repeat for the number of times
loaded into this register.

Name ACNT7 ACNT6 ACNT5 ACNT4 ACNT3 ACNT2 ACNT1 ACNT0
Default 0 0 0 0 0 0 0 0
Bits 0 to 7/Alternating Word-Count Rate Bits 0 to 7 (ACNT0 to ACNT7). ACNT0 is the LSB of the 8-bit
alternating word-count rate counter.
