Storage control apparatus, storage apparatus, storage control method, and computer-readable recording medium for executing a command based on data in received packet

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.

Serial type interface circuit, power saving method thereof, and device having serial interface
