Notes 1: When the oscillation frequency has a duty cycle of 50%.
2: When using the microcomputer in low-speed mode, set the clock input oscillation frequency on condition that f(XCIN) < f(XIN)/3.
3: 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.
