Abstract: An electronic device includes: a memory configured to a program; and one or more processors configured to execute the program stored in the memory. The one or more processors are connected to a first circuit and a second circuit, the first circuit being configured to execute a first operation cyclically and output an interrupt signal corresponding to the first operation, the second circuit being configured to execute a second operation in response to an operation instruction. In response to receiving the interrupt signal, the one or more processors output the operation instruction to the second circuit such that the second operation is not executed in a period in which the first operation affects the second operation.

Abstract: An electronic apparatus includes a first power feeder, a positioning-satellite-signal receiver, and a CPU. The first power feeder receives power from an external device and feeds the power to a secondary battery. The positioning-satellite-signal receiver receives a satellite signal transmitted by a positioning satellite. The CPU limits a receiving operation of the positioning-satellite-signal receiver when the first power feeder is receiving the power from the external device.

Abstract: Disclosed is a stepping motor including a rotor, a plurality of coils and a switching mechanism. The stepping motor simultaneously or sequentially applies driving pulses to the coils to rotate the rotor by a predetermined step angle, and while the driving pulses are being applied to part of the coils, the switching mechanism switches the rest of the coils other than the part of the coils driven by the driving pulses into a high impedance state.

Abstract: An electronic apparatus includes a secondary battery, a first power feeder, a second power feeder, and a processor. The first power feeder feeds power to the secondary battery. The second power feeder feeds power to the secondary battery at a current larger than a current fed by the first power feeder. The processor detects a voltage of the secondary battery, and determines a remaining power of the secondary battery based on a comparison of the detected voltage with first or second reference values. The first reference value is a predetermined value set in accordance with the current fed by the first power feeder. The second reference value is a predetermined value set in accordance with the current fed by the second power feeder, and is higher than the first reference value.

Abstract: An electronic timepiece includes a secondary battery, a first power feeder, a second power feeder, and a processor. The first power feeder feeds power to the secondary battery. The second power feeder feeds power to the secondary battery at a current larger than a current fed by the first power feeder. The processor determines remaining power of the secondary battery based on different references that are a reference of when the first power feeder is feeding the power to the secondary battery and a reference of when the second power feeder is feeding the power to the secondary battery.
