Abstract
A system comprises a semiconductor integrated circuit including a data processing unit that operates in any of a plurality of states, and a selection unit that selects a state from the plurality of states in accordance with a voltage supplied from a power supply unit and makes the data processing unit operate in the selected state, and a power supply unit including a control unit that starts supplying a voltage to the semiconductor integrated circuit based on an initial voltage value setting at startup and makes a voltage to be supplied transit to a predetermined voltage based on information of voltage value in response to a supply voltage having reached the initial voltage value, wherein the selection unit switches the data processing unit to a predetermined state when a supplied voltage has reached the predetermined voltage value from the initial voltage value.
