ABSTRACT:
A power supply circuit outputs different set potentials in response to control signals, wherein a voltage detecting circuit changes levels of a first reference potential and a second reference potential in response to inputs of control signals, and a clock generating circuit increases a frequency of the frequency divided clock signal when the levels of the first reference potential and the second reference potential are greatly changed in response to the inputs of the control signals.
