Note
Refers to the voltage with which the POC circuit cancels an internal reset. If V

, the internal reset
is canceled.
From the time of V

Remark
For the resonator selection and oscillator constant, customers are required to either evaluate the
oscillation themselves or apply to the resonator manufacturer for evaluation.
