Abstract:
1. An electronic timepiece comprising: a coil; a mode setting unit for switching an operation mode between a data receive mode and a normal operation mode; a synchronization signal generating unit for generating, when said operation mode is in said data receive mode, a synchronization signal that is synchronized to an external synchronization signal transmitted from an external transmitting device; and a received data generating unit for generating, when said operation mode is in said data receive mode, a received data on the basis of the synchronization signal and a data voltage signal induced around the coil by a transmitted data signal input from the external transmitting device, and outputting the received data; wherein the mode setting unit shifts said operation mode to the normal operation mode when the external synchronization signal is not inputted within a predetermined period during said data receive mode.
