Abstract

PURPOSE:To provide the integrated circuit for an electronic timepiece which can commonly be used with a display device being different in a display digit, by a method wherein a display switching terminal is mounted, and the terminal is earthed or connected to a power source to switch a key switch function and display timing. CONSTITUTION:If a display switching terminal 20 forms an earthing level or a power source level by an external bonding corresponding to a display digit, an AND-OR ROM17, assigning a switch function, is changed over to switch an assigned function of switches SW1-SW3 through a key input circuit 16. A mode, corresponding to the assigned function, is stored in the FF of a mode control circuit 18, and displaying counters 4-11, such as various types of times corresponding to selected display digits, are assigned corresponding to the mode. Meanwhile, by means of a level corresponding to the selection display digit of the terminal 20, a timing signal, controlling a display information memory circuit 14, from a timing control circuit 19 is switched corresponding to a display digit. This constitutes an integrated circuit for electronic watch which can commonly be used with a display device being different in a display digit.
