2.0

Note Refers to the voltage with which the POC circuit releases 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.
