ERR_CNT[15:0]:
The ERR_CNT[15:0] register is the number of error in the PRBS bytes detected during the
monitoring. Errors are accumulated only when the monitor is in the synchonized 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 trigger by an indirect write to this register or writing
register 0000H for a global performance monitor update. The error counter will not wrap
around after reaching FFFFH. It will saturate to this value.
