Abstract
A semiconductor device according to one embodiment selects one of the first and second resolver/digital converters and interrupts a supply of a power supply voltage to the other one of the first and second resolver/digital converters, and when an error is detected in the selected one of the first and second resolver/digital converters, the semiconductor device starts the supply of the voltage to the other one of the first and second resolver/digital converters, and switches the one of the first and second resolver/digital converters to the other one of the first and second resolver/digital converters.
