When Configuring the system to wake up on multiple gpio pins I have so far been able to see in the IRQ RAW register what source was waking up the M3. but now I have a situation that the M3 core gets an IRQ46 (GPIO) but I have no indication in any register why? all IRQ registers is 0.
Is this expected ?? was it just pure luck that I used to get any indication ??. the manual is not very clear on what should happen.
