Notes 1: When the A/D converter is used, refer to the recommended operating condition for A/D conversion.
2: Oscillation start voltage and oscillation start time depend on the oscillator, the circuit constant and temperature.
Especially, be careful that an oscillation start of the high-frequency oscillator may be difficult at low-voltage.
Until the oscillation is stabilized, wait in the on-chip oscillator mode.
