The ERR_CNT[15:0] register is the number of errors in the PRBS bytes detected during
monitoring. Errors are generally accumulated only when the monitor is in the synchronized
state. Even if there are multiple errors within one PRBS byte, only one error is counted. The
transfer of the error counter to this holding register is triggered by an indirect write to the
PRGM Performance Counters Transfer Trigger register for the particular STS-12 slice
(register 080CH, 081CH, 082CH or 083CH respectively) or by writing to register 0000H for
a global performance monitor update. Do not write to this register. The error counter will not
wrap around after reaching FFFFH. It will saturate to this value.
Note that the 3 errors which cause the PRGM to lose synchronization may be counted as 3, 4,
or 5 errors.
