It is recommended that you keep the rising
speed to no more than 50 mV/ms.
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 that you raise the voltage at a
steady rate, in order to suppress fluctuations (see figure below). In this case, perform this operation
when the PLL clock is not being used. If, however, the voltage falling speed is no more than 1 V/s,
it is permissible to perform this operation while using the PLL clock.
