Notes 1.
When using at f

= 4 MHz or higher, it is necessary to design the application circuit so that the RESET
pin goes low when the supply voltage is less than 2.7 V.

Notes 1.
Operates effectively under the conditions of f

= 2.4 to 4 MHz.
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

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