ABSTRACT:
Where a system including a main computer with a source battery for generating a system source voltage and a peripheral device having higher operating voltage than the system source voltage and a source voltage generator circuit which generates a source voltage corresponding to this operating voltage, supply of system source voltage from the source battery is prohibited and the source voltage from the source voltage generator circuit of the peripheral devices is used as the system source voltage of the entire system when the main computer is driving the peripheral device such that the consumption of the source battery for the main computer can be reduced.
