How can I enable interrupt support for the HLGPI[13:0] input-only pins?

Environment

  • Quartus® II Subscription Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    The HLGPI[13:0] input-only pins of the Cyclone® V SX device share pins with the HPS DDR controller. To identify the pin location for these GPI pins, see the related solution.

    Physically the HLGPI[13:0] signals are connected to GPIO2_porta_input[13:26] in the HPS. You can configure the HLGPI to generate interrupts just like other GPIO in GPIO2 component.  

    To configure the GPIO interrupts, configure the following registers - gpio_inten, gpio_intmask, gpio_inttype_level, and the gpio_int_polarity registers.  These registers can be found in the address map for the Cyclone V HPS device at the Cyclone V HPS Register Address Map and Definitions web page.
