should be lower than 0.2 V before power supply rise.
Notes: The above values are the values required for a power-on reset
.When HST = “L”, this standard must be followed to turn on power supply for power-on reset whether or
not necessary.
The device has built-in registers which are initialized only by power-on reset. For possible initialization of
these registers, turn on power supply according to this standard.

The gradient should be no
more than 50mV/ms.
Abrupt changes in the power supply voltage may cause a power-on reset.
When changing the power supply voltage during operation, the change should be
as smooth as possible, as shown in the following figure.
