must be kept lower than 0.2 V before power-on.
The above values are used for creating a power-on reset.
Some registers in the device are initialized only upon a power-on reset. To initialize these register, turn on
the power supply using the above values.

Sudden changes in the power supply voltage may cause a power-on reset.
To change the power supply voltage while the device is in operation, it is recommended to
raise the voltage smoothly to suppress fluctuations as shown below.
In this case, change the supply voltage with the PLL clock not used. If the voltage drop is
1 V or fewer per second, however, you can use the PLL clock.
It is recommended to keep the rising speed of
the supply voltage at 50 mV/ms or slower.
