Abstract

L'invention concerne une pièce d'horlogerie électronique dont le circuit intégré comporte un circuit permettant l'ajustement de la fréquence en dépendance d'une information présente à ses entrées, information qui dépend d'un certain nombre de bornes utilisées à cette fin. Le but de l'invention est d'augmenter le nombre d'informations à introduire pour un nombre déterminé de bornes réservées à cet usage. Dans ce but, le circuit intégré comporte un premier groupe de m bornes et un circuit d'introduction muni d entrées d'information reliées à un second groupe de n bornes du circuit intégré, chacune des n bornes de ce second groupe étant susceptible d'être reliée par une connexion extérieure au circuit intégré à l'une des m bornes du premier groupe, de sorte que le circuit d'introduction délivre une information distincte pour chacune des m**n combinaisons possibles desdites connexions.
