8.1 LINE CODE VIOLATION COUNT REGISTER (LCVCR)
Line Code Violation Count Register 1 (LCVCR1) is the most significant word and LCVCR2 is the least
significant word of a 16–bit counter that records code violations (CVs). CVs are defined as Bipolar
Violations (BPVs) or excessive zeros. See Table 8-1 for details of exactly what the LCVCRs count. If the
B8ZS mode is set for the receive side via CCR2.2, then B8ZS code words are not counted. This counter is
always enabled; it is not disabled during receive loss of synchronization (RLOS=1) conditions.
