It is recommended that the rate of
increase in the voltage be kept to
no more than 50 mV/ms.
Abrupt changes in the power supply voltage may cause a power-on reset.
When changing the power supply voltage during operation, suppress variations in the voltage and
ensure that the voltage rises smoothly, as shown in the following figure.
