Hi,

You need an external input to wake up from System OFF mode. From infocenter:

System OFF is the deepest power saving mode the system can enter. In this mode, the system’s core functionality is powered down and all ongoing tasks are terminated.

The device can be put into System OFF mode using the POWER register interface. When in System OFF mode, the device can be woken up through one of the following signals:

The DETECT signal, optionally generated by the GPIO peripheral

The ANADETECT signal, optionally generated by the LPCOMP module

The SENSE signal, optionally generated by the NFC module to “wake-on-field”

A reset

When the system wakes up from System OFF mode, it gets reset.
