Abstract

An electronic timepiece control circuit for facilitating the selection of a preferred function in a multi-functional electronic timekeeping circuit wherein each function can also be selected cyclicly in sequence, is provided. The timekeeping circuit is adapted to be disposed in at least three timekeeping functional modes to perform at least one distinct timekeeping function in each functional mode in response to a function control signal being applied thereto. Mode select circuitry is coupled to the timekeeping circuit for cyclicly selecting, in sequence, each timekeeping functional mode of the timekeeping circuit in response to each mode select signal applied thereto. A judgment circuit is coupled to thetimekeeping circuit and is adapted to return the timekeeping circuit to a predetermined timekeeping functional mode in response to a mode select signal and a function control signal being coincidentally applied thereto.
