The serializer(41), installed within the mode select controller(40), converts the received parallel digital values into serial bit frame signals based on a reference CPU clock generated from a clock generator(10). So the serializer(41) transmits the frame signal corresponding to the power mode to the CPU(60) via a single serial signal line. The CPU(60) makes a frame analyzer(61) receive the frame signal, extract 4 bit data signal from the frame signal, and check the a value of the extracted digital signal to determine a power mode of the CPU(60).
