Hi,

   

I am using CY8C20346A, I want to know the minimal time width for a gpio input pulse (high-low-high) to create a GPIO interrupt. IOINT==1.

   

I can not find this info in datasheet.

   

Thanks.

   

BR.

If you look at 63/64 in TRM looks like GPIO clocks, via edge, an ISR request

   

into ISR controller. I interpret this this to be setting a D or something akin.

   

 

   

No precise timing is given however. The latency/response covered in Interrupt

   

Controller section of TRM.

   

 

   

Regards, Dana.
