Note 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, a 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.
