6.2 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 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 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 6-2 for a detailed description of exactly what errors the PCVCR counts.

LSB of the 12-Bit CRC6 Error or Frame Bit Error Count (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).

6.3 Multiframes Out of Sync Count Register (MOSCR)
Normally, the MOSCR is used to count the number of multiframes that the receive synchronizer is out of
sync (RCR2.0 = 1). This number is useful in ESF applications needing to measure the parameters Loss Of
Frame Count (LOFC) and ESF Error Events as described in AT&T publication TR54016. When the
MOSCR is operated in this mode, it is not disabled during receive loss of synchronization (RLOS = 1)
conditions. The MOSCR has alternate operating mode whereby it will count either errors in the Ft
framing pattern (in the D4 mode) or errors in the FPS framing pattern (in the ESF mode). When the
MOSCR is operated in this mode, it is disabled during receive loss of synchronization (RLOS = 1)
conditions. See Table 6-3 for a detailed description of what the MOSCR is capable of counting.
