Extreme variations in voltage supply may activate a power-on reset.
As the illustration below shows, when varying supply voltage during operation the use of a smooth
voltage rise with suppressed fluctuation is recommended. Also in this situation, the PLL clock on the
device should not be used, however it is permissible to use the PLL clock during a voltage drop of
1V/s or less.

A rise slope of 50 mV or
