Hello community,


We hope to use a gpio input for external interrupt.

To detect low input as interrupt by GPIO module, how long does it keep low level?

How about rise/fall edge detect setting?


The other hands, we hope to know how long it must keep Hi/Low level

for general purpose input signal?


It has a same question in this thread.

But no answer it have.


Don't you have some information about it?


Best regards,
