NOTES:
1. When using A/D converter, see A/D converter recommended operating conditions.
2. The start voltage and the start time for oscillation depend on the using oscillator, oscillation circuit constant value and operating
temperature range, etc.. Particularly a high-frequency oscillator might require some notes in the low voltage operation.
3. When the oscillation frequency has a duty cycle of 50%.
4. When using the microcomputer in low-speed mode, set the sub-clock input oscillation frequency on condition that f(XCIN) < f(XIN)/3.
