No, you need to use one extra timer. So say TIMER1 you use as normal timer, trigger every 1 second, and TIMER2 use it as the counter and connect it to GPIO.

Are the two events sharing the same counter value and not having synchronization issues? gpio events can occur from time to time and timeouts occur every second.

Yes, but what is the problem ? I don't see any problem here.

Yes, that's right. You understand exactly.

Hi,

What exactly the issue you are thinking of ? My understanding is you use the GPIO event and trigger a counter (you can do it with PPI without CPU needed). And then you send the value of the counter on each timer timeout event ?
