ABSTRACT:
An integrated circuit comprises components for the basic functions of a timepiece and additional components for controlling the operation mode of the basic components. By properly controlling the operation mode of the basic components, the integrated circuit can be applied to two or more types of timepieces, thereby reducing the kinds of the integrated circuits that need to be prepared.
