must be kept lower than 0.2 V before power-on.
Notes: The above ratings are values for causing a power-on reset.
There are internal registers which can be initialized only by a power-on reset.
Apply power according to this rating to ensure initialization of the registers.

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 mV 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.
