Abstract
PURPOSE:To achieve automatic resetting, by sending a resetting signal by comparing a signal applied to an input port and that from an output port in a resetting circuit system which uses a microcomputer. CONSTITUTION:While a microcomputer 10 is operating normally according to a program and the output X of the output port of the microcomputer 10 is the same as a signal applied to an input terminal IN, the output of a comparing and deciding circuit 20 never changes. If the computer is not in the normal programmed operation owing to a noise, etc., namely, when the output X of the output port is different from the signal to the input terminal IN, the circuit 20 outputs a constant- width resetting signal Y repetitively until the microcomputer returns to the normal operation, thus achieving automatic resetting.
