The device POWER ON enable conditions are as follows:
Interrupt flag active generates a POWER ON enable condition pulse of length tDOINT1 only when the device is in the OFF state (when the NRESPWRON signal is low). The POWER ON enable condition pulse occurs only if the interrupt status bit is initially low (no previous interrupt pending in the status register). The interrupt status register must first be cleared to let the device power off during the tDOINT1 pulse duration.
GPIO2 cannot be used to turn on the device, even if its associated interrupt is not masked. The GPIO0, GPIO1, GPIO3, GPIO4, or GPIO5 signals can be used to turn on the device, if its associated interrupt is not masked.
The watchdog interrupt is not a power-on event, but can wake up the device from sleep mode.
