Abstract
A power saving of a serial interface circuit decreases the unnecessary power consumption of a serial interface circuit, while decreasing the return time and expanding the power saving range. Gates are disposed for stopping the clock supply to a digital portion of the interface circuit while maintaining operation of clock sources in the digital portions. Therefore a quick shift to and return from the power save mode by stopping and restarting clocks is implemented, which further decreases power consumption.
