Method of and circuit for controlling a clock
This invention relates to switching-over to a higher speed clock from a lower speed clock. The switching-over of the clock is performed before, after, or simultaneously to a transition to a sleep mode is carried out. After the switching-over of the clock is performed, if oscillation of the high speed clock and an internal voltage are stabilized, it is returned to a normal mode from the sleep mode.
