Bits 0 to 15: BERT 24-Bit Error Counter (BEC8 to BEC23). Upper two bytes of the 24-bit counter. This 24-bit
counter will increment for each data bit received in error. This counter is not disabled when the receive BERT loses
synchronization. This counter can be cleared by toggling the LC control bit in BERTBC0. This counter saturates
and will not rollover. Upon saturation, the BECO status bit in the BERTEC0 register will be set. This error counter
starts counting when the BERT goes into receive synchronization (RLOS = 0 or SYNC = 1) and it will not stop
counting when the BERT loses synchronization. It is recommended that the host toggle the LC bit in BERTC0
register once the BERT has synchronized and then toggle the LC bit again when the error checking period is
complete. If the device loses synchronization during this period, then the counting results are suspect.
