Please if anyone can explain this to me!Thanks in advance.
A minimum pulse width on EXTI is enough to trigger the interrupt. This minimum pulse width is not dependant an th APB2 clock frequency,
But is likely dependent on the resychronizer at the pin.
this has been discussed a couple of months ago, and as Edison from the ST Prague support group confirmed, EXTI is surprisingly asynchronous.
Just plugging in the link: EXTI minimal pulse length clarification
Thank you all for helping me !!
