2.
Refers to the voltage with which the POC circuit cancels an internal reset. If V
POC
< V
DD
, the internal
reset is canceled.
From the time of V
POC
≥
V
DD
until the internal reset takes effect, lag of up to 1 ms occurs. When the
period of V
POC
≥
V
DD
lasts less than 1 ms, the internal reset may not take effect.
