should be lower than 0.2 V before power supply rise.
Notes: The above specifications are the numeric values needed for causing a power-on reset.
There are built in resisters initialized only by power on reset in the device.
Turn on power supply according to the specification at the point of this initialization.

A rise time of 50 mV/ms or less
is recommended.
An abrupt change in the supply voltage may activate power-on reset.
If the supply voltage must be changed during operation, the voltage change should be smooth without
sudden fluctuations.
