Note Refers to the voltage with which the POC circuit cancels an internal reset. If VPOC < VDD, the internal reset

is canceled.

From the time of VPOC

≥ VDD until the internal reset takes effect, lag of up to 1 ms occurs. When the period

of VPOC

≥ VDD lasts less than 1 ms, the internal reset may not take effect.

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.
