Note
The TYP value differs depending on the setting of the oscillation stabilization time select register (OSTS).
Caution Ensure that the duty of oscillation waveform is between 45% and 55%.
Remarks 1.
Connect the oscillator as close as possible to the X1 and X2 pins.
Do not route the wiring near broken lines.
For the resonator selection and oscillator constant, customers are required to either evaluate the
oscillation themselves or apply to the resonator manufacturer for evaluation.
