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.
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-
rupt reported by INT if not masked by the CNTOV_IM (b0, INTM2,...).
