6.2 Path Code Violation Count Register (PCVCR)
When the receive side of the DS2151Q 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 codewords. 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 DS2151Q 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 6-2 for a detailed description of exactly what errors the PCVCR counts.
PCVCR1: PATH VIOLATION COUNT REGISTER 1 (Address = 25 Hex)

(Note 2)
Note 1: The upper nibble of the counter at address 25 is used by the Multiframes Out of Sync Count Register.
Note 2: PCVCR counts either errors in CRC codewords (in the ESF framing mode; CCR2.3 = 1) or errors in the framing bit position (in the
D4 framing mode; CCR2.3 = 0).
