NAME AND DESCRIPTION
MSB of the 32–bit Bit Counter
LSB of the 32–bit Bit Counter
BERT Bit Counter (BBC0/ BBC1/ BBC2/ BBC3).
Once BERT has achieved synchronization, this
32-bit counter will increment for each data bit (i.e. clock) received. Toggling the LC control bit in BC0
can clear this counter. This counter saturates when full and will set the BBCO status bit.
BEC0: BERT Error Count Register 0 (Address = 4D Hex)
BEC1: BERT Error Count Register 1 (Address = 4E Hex)

NAME AND DESCRIPTION
MSB of the 24–bit Error Counter
LSB of the 24–bit Error Counter
BERT Error Counter (BEC0/ BEC1/ BEC2).
Once BERT has achieved synchronization, this 24-bit
counter will increment for each data bit received in error. Toggling the LC control bit in BC0 can clear
this counter. This counter saturates when full and will set the BECO status bit.
