If you change the power supply voltage too rapidly, a power-on reset may occur.
We recommend that you start up smoothly by restraining voltages when changing
the power supply voltage during operation, as shown in the figure below. Perform
while not using the PLL clock. However, if voltage drops are within 1 V/s, you can
operate while using the PLL clock.
