ABSTRACT:
A coincidence detecting circuit is connected to multiple output lines of the microprocessor, and for resetting a microprocessor in response to a nondetection of coincidence within a predetermined period. The time sequence of pulses on one of the lines is changed by lengthening the pulses so as to coincide with signals on other channels. The operating program of the microprocessor is altered, if necessary, so as to produce signals on plural channels having predetermined time relationships with each other.
