Abstract:
An electronic timepiece includes: a latch unit that latches and outputs specification data designating a specification in accordance with a latch signal; a signal output unit that outputs one of a plurality of driving signals including driving pulses at different periods based on the specification data output from the latch unit; a driving unit that drives a motor based on the driving signal output from the signal output unit; and a control unit that generates the latch signal so that the latch signal has at least an active level at a timing before generation of each driving pulse in the driving signal with a shortest period of the driving pulse among the plurality of driving signals.
