Abstract
Système de bus de communication de données pour transférer des signaux de contrôle entre au moins deux modules. Le système comprend les lignes 5 et 7 sur lesquelles sont transmis à partir du module initiateur 1 respectivement un signal de module initiateur et un signal d'échantillonnage, et les lignes 9 et il sur lesquelles sont transmis à partir du module suiveur 3 respectivement un signal de module suiveur et un signal d'échantillonnage. Le dispositif 15 sert à contrôler la validité des signaux ainsi que la synchronisation de la séquence. Cette structure de bus permet en plus du transfert de données de vérifier la validité et la synchronisation des signaux de contrôle transmis entre les 2 modules.
