Figure-30 Automatic Error Counter Updating
3.5.6.2 Manual Error Counter Updating
When the CNT_MD bit (b1, ERR,...) is ‘0’, the Error Counter is
updated manually.
When there is a transition from ‘0’ to ‘1’ on the CNT_STOP bit (b0,
ERR,...), the Error Counter transfers the accumulated error numbers to
the ERRCH and ERRCL registers and the Error Counter will be cleared
to start a new round counting. The ERRCH and ERRCL registers should
be read in the next round of error counting, otherwise they will be over-
written.
When the ERRCH and ERRCL registers are all ‘1’s and there is still
error to be accumulated, the registers will be overflowed. The overflow is
indicated by the CNTOV_IS bit (b0, INTS2,...) and will induce an inter-
