Note : Extreme variations in power supply voltage may trigger a power-on reset. When the power
supply voltage is changed during operation, it is recommended that increases in the voltage
smoothed out as shown in the following diagram. The PLL clock of the device should not be
in use when varying the voltage. However, the PLL clock may continue to be used if the rate
of the voltage drop is 1 V/s or less.
