5.1 Line Code Violation Count Register (LCVCR)
Line Code Violation Count Register 1 High (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 0s. See Table 5.1 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.

5.2 Path Code Violation Count Register (PCVCR)
When the receive side of the DS2152 is set to operate in the ESF framing mode (CCR2.3=1), PCVCR
will automatically be set as a 12-bit counter that will record errors in the CRC6 code words. When set to
operate in the D4 framing mode (CCR2.3=0), PCVCR will automatically count errors in the Ft framing
bit position. Via the RCR2.1 bit, the DS2152 can be programmed to also report errors in the Fs framing
bit position. The PCVCR will be disabled during receive loss of synchronization (RLOS=1) conditions.
See Table 5-2 for a detailed description of exactly what errors the PCVCR counts.
