Claims (1)
信号を該マイクロコンピユータでソフト的に分周
させると共に、外部回路においても同じ分周比で
ハード的に分周し、さらにソフト分周出力とハー
ド分周出力を同期化してから両分周出力の一致判
断をして、不一致のとき該マイクロコンピユータ
をリセツトする信号を発生するようにしてなるこ
とを特徴とする暴走検出回路。 The pulse signal given to the microcomputer from the outside is divided by software in the microcomputer, and the external circuit is also divided by hardware at the same division ratio, and furthermore, the software division output and the hard division output are synchronized. 1. A runaway detection circuit characterized in that it determines whether the two frequency-divided outputs match each other, and generates a signal to reset the microcomputer when they do not match.
