Notes 1. Operates effectively under the conditions of fX = 2.4 to 8 MHz.
2. Refers to the voltage at which the POC circuit cancels an internal reset. If VPOC < VDD, the internal
reset is released.
From the time of VPOC ≥ VDD until the internal reset takes effect, a delay of up to 1 ms occurs. When
the period of VPOC ≥ VDD lasts less than 1 ms, the internal reset may not take effect.
