| Summary: | An oscillation circuit generates a reference clock signal for a clock signal supplied to each section of a data transfer control device. In a clock output control circuit, a clock command is decoded by a clock command decoder and oscillation of the oscillation circuit is controlled. The data transfer control device including a clock control circuit transfers data as a host or a peripheral in a state being set to either a self-powered first device or a second device which can operate by using a power supply on a bus. The oscillation operation of the oscillation circuit is suspended in an idle state of the second device. |
