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.

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.
