How looks a process of waking up BlueNRG-2 from deep sleep?

Question asked by Piotr Romaniuk on May 13, 2018

Hi,

I am confused by documentation of BlueNRG and various description of exiting from WFI for Cortex-M0.
What is going on when BlueNRG-2 is woken up from deep sleep by external gpio pin?
Is the program continuing execution at instructions following WFI, or it causes a reset and starts from ResetHandler?

 

In my program interrupts are disabled before WFI.

 

Regards,
Piotr Romaniuk
