    a gpio interrupt question

    jingwei.tan

      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.

          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.
