Abstract
Such a device is disclosed that includes a clock generation circuit generating a first clock signal and having an output node, and a drive circuit coupled to the output node of the clock generation circuit. The clock generation circuit outputs the first clock signal from the output node to the drive circuit in a clock output mode, fixes a potential of the output node to a first level in a first clock stop mode, and fixes the potential of the output node to a second level that is different from the first level in a second clock stop mode.
