– APRIL 2006 – REVISED JANUARY 2011

When the device is powered up, the POR sets the device in default mode when AVDD reaches 1.5 V. When the

device is powered down, the POR circuit requires AVDD to remain below 125 mV for a duration of at least 350

ms to ensure proper discharging of internal capacitors and to correct the behavior of the device when powered

up again. If AVDD drops below 400 mV but remains above 125 mV, the internal POR capacitor does not

discharge fully and the device requires a software reset to perform correctly after the recovery of AVDD (this is

shown as the undefined zone in Figure 65).
