Abstract

PURPOSE:To offer LSI for electronic timepiece which has selectable specifications, by externally controlling control terminals provided to LSI. CONSTITUTION:To select one of specification A consisting of a timepiece function, stopwatch function, dual time function, and alarm function, specification B of the timepiece function, stopwatch function and dual time function, specification C of the timepiece function and stopwatch function, and specification D with only the timepiece function, supplying signals to control terminals CT1 and CT2 provided to LSI, are outputted specification selective signals MA-MD from gate circuits 3-6. Those specification selective signals MA-MD are supplied to gate circuits 7, 8, 10, 11, and 12 and every time mode change-over switch S is operated, flip-flops N1 and N2 vary in output to select respective functions according to those specifications.
