These registers indicate the number of LCV error events that occurred during the
previous accumulation interval. An LCV event is defined as the occurrence of a
Bipolar Violation or Excessive Zeros (>7 consecutives zeros for T1 B8ZS, >15
consecutive zeros for T1 AMI, or >3 consecutive zeros for E1 AMI or E1 HDB3).
The counting of Excessive Zeros can be disabled by the BPV bit of the Receive
Interface Configuration register.
