nRF52832 System OFF with Wake on Reset

[Mark J]

The latest rev of the product spec (1.1 when this was posted) includes a table on page 77 that indicates that the System OFF draw depends on a wakeup source (e.g. GPIO, NFC, reset, etc). Links to Product Specs including this rev: Product Specs in pdf format

Support for going into System OFF does not seem to include specifying a wakeup source. Specifically, calling sd_power_system_off() or setting NRF_POWER->SYSTEMOFF = 1.

Is there another way to specify and limit the source of wakeup to reset to get a lower power draw when in System OFF?

Hi Øyvind,

How do I determine the wake up source after going into low power?

Thank you Riyad

There is register for it (applies if you boot from any situation, not only power off).
