8. ERROR COUNT REGISTERS
There are a set of three counters that record bipolar violations, excessive zeros, errors in the CRC6 code
words, framing bit errors, and number of multiframes that the device is out of receive synchronization.
Each of these three counters are automatically updated on either one second boundaries (CCR3.2=0) or
every 42 ms (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 42 ms. The user can use the
interrupt from the one second timer to determine when to read these registers. The user has a full second
(or 42 ms) 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 over-flow but the bit error would have to exceed 10E-2 before this would occur).
