Bit 2/Receive All-Zeros Condition (BRA0)
Bit 3/Receive All-Ones Condition (BRA1)
Bit 4/BERT Error-Counter Overflow Event (BECO)
Bit 5/BERT Bit-Counter Overflow Event (BBCO)
Bit 6/Bit-Error Detected Event (BBED)
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.
