Abstract
There is expected a technique capable of determining a power supply state with respect to an arithmetic unit according to a connection status with a power supply unit. The arithmetic unit includes a state management circuit outputting a state signal indicating whether or not supply of power from the power supply circuit is valid. The state management circuit of the arithmetic unit determines a value of the state signal based on a voltage of a second port, a voltage of a first port, and a signal indicating whether or not the power supply unit exists.
