Figure 2 Operating Voltage vs. Main Clock Operating Frequency (Dual-clock MB8916X/A)
Figures 1 and 2 indicate the operating frequency of the external oscillator at an instruction cycle of 4/FCH.
Since the operating voltage range is dependent on the instruction cycle, see minimum execution time if the
operating speed is switched using a gear.
