Abstract

L'invention concerne une unité de microcontrôleur ayant un mode de fonctionnement de suspension comprenant un circuit de traitement pour recevoir des informations numériques et traiter lesdites informations numériques reçues. Un circuit de temporisation génère des signaux de temporisation vers le circuit de traitement en réponse à des signaux reçus depuis un circuit d'horloge générant à la fois un signal d'horloge interne et un signal d'horloge externe. L'invention concerne également un circuit pour commander l'application sélective d'un signal d'horloge externe synchronisé et du signal d'horloge externe au circuit de temporisation. Le circuit applique le signal d'horloge externe synchronisé au circuit de temporisation dans au moins un mode de fonctionnement actif de l'unité de microcontrôleur en réponse à au moins un premier signal de commande et applique le signal d'horloge externe au circuit de temporisation dans au moins un mode de fonctionnement de suspension de l'unité de microcontrôleur en réponse à au moins un signal de commande de suspension.
