NRF9160 POFWARN

[Thomas]

Hi,

I was investigating the registers of the nrf9160 using segger embedded studio and found POFCON, which is not mentioned in the documentation.

Can you provide the documentation for this? Also, what is the best way to get access to the POFWARN interrupt? From what I see nrf_power_clock.c is using the interrupt for the clock without allowing access to the power interrupts? 

Kind regards,

Thomas

Thank you for the updates Thomas. We're currently looking into both the BOR versus power on resets and the %XPOFWARN AT command. I will update you with the progress as soon as possible, but it might be a few days. Thank you for your patience.

Best regards,

Simon

UPDATE: AT%XPOFWARN is not available in mfw v1.2.0, but should definitely be available for mfw v1.2.1 and onwards. Can you provide an AT sequence log similar to the one below where you're using mfw v1.2.1?

Thanks for looking into this Simon.

Is this what you are after?
