    FX3 GPIF - Intr_CPU recovery time / frequency

    FaFi_4159091

      Hello,

       

      I have a very simple callback (toggles a single pin via direct register access) registered to the Intr_CPU function in GPIF. My GPIF design calls Intr_CPU every 15 us and the pin is toggled almost immediately, which indicates a acceptable latency. However, only every thirtd interrupt is executed, as if there is some recovery time after the last intr_cpu before the next can be called. The callback function takes definitely a lot less than 15 us to return.

       

      Is there a way around this?
