6 ERROR COUNT REGISTERS
There are a set of three counters in the DS2152 that record bipolar violations, excessive 0s, errors in the
CRC6 codewords, framing bit errors, and number of multiframes that the device is out of receive
synchronization. Each of these three counters is automatically updated on either 1-second boundaries
(CCR3.2 = 0) or every 42ms (CCR3.2 = 1) as determined by the timer in Status Register 2 (SR2.5).
Hence, these registers contain performance data from either the previous second or the previous 42ms.
The user can use the interrupt from the 1-second timer to determine when to read these registers. The user
has a full second (or 42ms) to read the counters before the data is lost. All three counters will saturate at
their respective maximum counts and they will not rollover (note: only the Line Code Violation Count
Register has the potential to overflow but the bit error would have to exceed 10-2 before this would
occur).
6.1 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 6-1 for details of exactly what the LCVCRs count. If the
B8ZS mode is set for the receive side via CCR2.2, then B8ZS codewords are not counted. This counter is
always enabled; it is not disabled during receive loss of synchronization (RLOS = 1) conditions.
