Caution Ensure that the duty of the oscillation waveform is between 45% and 55%.
Remarks 1.
Connect the oscillator as close as possible to the XT1 and XT2 pins.
Do not route the wiring near broken lines.
For the resonator selection and oscillator constant, customers are requested to either evaluate the
oscillation themselves or apply to the resonator manufacturer for evaluation.
