Notes 1: When the A-D converter is used, refer to the recommended operating condition for A-D conversion.
2: When using the microcomputer in low-speed mode, set the clock input oscillation frequency on condition that f(XCIN) < f(XIN)/3.
3: When the timer X count source selection bit is set to “1”, as for the recommended operating condition of the main clock input frequency f(XIN), the rating
value at the high-speed mode is applied.
4: 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 ring oscillator mode.
