Abstract

An integrated circuit of this invention includes a processor, a first circuit for generating a clock signal, and a second circuit for selecting a suitable line voltage. The first circuit generates at least two kinds of clock signals. When one kind of clock signal having a high frequency is selected for use, the processor gives an instruction to the second circuit so as to change the connection between external batteries, and so, to obtain a high line voltage. On the contrary, when the other kind of clock signal having a low frequency is selected for use, said processor gives an instruction to the second circuit so as to change the connection between the batteries, and so, to obtain a low line voltage.
