Abstract:
An electronic device includes a power supply circuit, a first counter that counts the number of times that supply of external power to the power supply circuit is stopped, a second counter that is operated by a first power and counts the number of times that generation of the plurality of kinds of power is stopped, a third counter counting the number of times that any of the plurality of kinds of power is dropped to a predetermined voltage or less, a non-volatile first memory storing status information indicating whether or not supply of the external power to the power supply circuit is properly stopped, and a fourth counter that counts the number of times that the supply of the external power to the power supply circuit is properly stopped and the number of times that the supply of the external power to the power supply circuit is abnormally stopped.
