I'm using 3 state machines to generate a DAC output and it's working fine. One machine generates the sample rate, another writes the DAC output, and a third outputs the wave heartbeat (scope trigger every repeating wave). I use multiple irq's to sync the state machines, but I see in the docs that it's possible to use irq rel to sync multiple state machines. Unfortunately, I don't understand how rel irqs provide that functionality. Can someone point me to a use case where irq rel is used to sync multiple state machines? I've googled to no avail to find something that makes sense.
