The below user program can monitor the status of ERR and I.ERR LEDs, and turn off LED automatically by the
light of LED. This sample program is in case the "open error" happens on ASR connection 1, which is specified as
positive station.
Set EC0 bit of MDCR to internal output M200 and EC1 bit to internal output M201 as well.
