Electronic timepiece

Image Number 2 for United States Patent #4336608.

An electronic timepiece comprising means to appreciably increase the number of distinctive information which can be introduced and, if necessary memorized, for a given number of terminals intended for that purpose, information needed for the adjustment of the frequency. The integrated circuit of the timepiece is provided with a first group of m terminals and it comprises an introduction circuit having inputs reserved to introduce the desired information, these inputs being connected to a second group of n terminals of the integrated circuit. The introduction circuit has also control inputs and each of the n terminals of the second group is capable to be connected, by a connection external to the integrated circuit, with one of the m terminals of the first group. The introduction circuit is arranged in such a way as to deliver to its outputs, at least periodically, one distinctive information for each of the m.sup.n possible combinations of the mentioned connections.
