Notes 1: When the A/D converter is used, refer to the recommended operationg conditions of the A/D converter.
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 dividing frequency selection bit and timer Y dividing frequency selection bit are “01(1/1
φSOURCE)” or “10(1/2 φSOURCE)”, the limits
at the high-speed mode are suitable for the recommended operating condition of main clock input frequency f(XIN).
4: The oscillation start voltage and the oscillation start time differ in accordance with an oscillator, a circuit constant, or temperature, etc. When power supply
voltage is low and the high frequency oscillator is used, an oscillation start will require sufficient conditions.
