ERROR COUNT REGISTERS
There is a set of three counters per framer 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 can be 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) or manually (CCR6.6=1 and triggering with CCR6.5). When updated automatically, 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).
