Main clock operating frequency (MHz) (at an instruction cycle of 4/FCH)
Figure 1 indicates the operating frequency of the external oscillator at an instruction cycle of 4/FCH.
Since the operating voltage range is dependent of the instruction cycle, see minimum execution time if the
operating speed is switched using a gear.
