Abstract
If a supply voltage reaches a voltage level that may lead to detection errors of a supply voltage detecting circuit, then a voltage detecting operation is prohibited if generation of power that can be charged into a high-capacity secondary power source is not detected, while the voltage detecting operation is continued if the generation of power that can be charged into the high-capacity secondary power source is detected.
