では不動作になるマイクロプロセッサ暴走監視回路にお
いて、上記監視回路の入力側に微分回路が挿入されたこ
とを特徴とするマイクロプロセッサ暴走監視回路。During normal operation of the microprocessor, pulses are periodically output from the microprocessor, and the pulses are input to the runaway monitoring circuit, and when the pulses are not input for a predetermined period of time, the runaway monitoring circuit detects this and outputs pulses from the microprocessor. In a microprocessor runaway monitoring circuit that outputs a reset signal to the microprocessor, and this runaway monitoring circuit becomes inoperable if a logic level of one polarity is input, a differentiating circuit is inserted on the input side of the monitoring circuit.
