Where can I find the references to module guide resources for the External Interrupt Request module on sf_external_irq?


Information on the module guide itself and the associated resources and known issues are available here.


The External IRQ Framework provides high-level APIs for applications using the external pin interrupts with the ThreadX RTOS. The Framework supports the external IRQ pins on the Synergy microcontroller.

The External IRQ Framework supports the following features:

  • Responds to external interrupt inputs
  • RTOS aware implementation using an internal semaphore for thread synchronization
    • Can signal internal threads
    • Can trigger transfers via the Event Link Controller (ELC)
  • Uses the port pins available on Synergy MCUs
    • Pins may differ between MCUs so refer to MCU User’s Manuals for specifics
  • Supports several hardware features such as
    • Channel selection
    • Trigger conditions
    • Digital filtering
    • Auto-start
