Wakeup from systemoff

[swathi p]

Hi,

Our application includes implementation of capacitive touch sensor through SAADC.I should initially wake up device from system off mode.Using SAADC is it possible to wakeup device?Please let me know possibility.

Thank you.

Hi,

See this link.

When in System OFF mode, the device can be woken up through one of the following signals:

1. The DETECT signal, optionally generated by the GPIO peripheral
2. The ANADETECT signal, optionally generated by the LPCOMP module
3. The SENSE signal, optionally generated by the NFC module to “wake-on-field”
4. A reset

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