5.0 ERROR COUNT REGISTERS
There are a set of three counters in the DS2143 that record bipolar violations, errors in the CRC4 SMF
code words, and E-bits as reported by the far end. Each of these three counters are automatically updated
on 1-second boundaries as determined by the 1-second timer in Status Register 2 (SR2.4). Hence, these
registers contain performance data from the previous second. The user can use the interrupt from the 1-
second timer to determine when to read these registers. The user has a full second to read the counters
before the data is lost.
