Figure 1 indicates the operating frequency of the external oscillator at an instruction cycle of 4/F
Since the operating voltage range is dependent on the instruction cycle, see minimum execution time if the
operating speed is switched using a gear.
Note: The shaded area is assured only for the MB89635/636/637.
