Research direction
Start with the referenced blog post and the documentation covering PIO IRQ instructions and RP1 interrupt behavior. Determine whether IRQ can synchronize two state machines and document the distinction between PIO-local use and interrupts routed between RP1 and the SoC; no source file or test is identified in the issue.
Written by the indexing model from the issue text.
Description
On the blog post it says One feature absent from this first release is interrupt support. RP1 provides two PIO interrupts, which can be triggered by the PIO instruction IRQ (interrupt request), and these could be used to trigger actions on the SoC.
Does this mean irq assembly command doesn't work at all or just between the rp1 and soc?
I want to sync two state machines with the irq like rp2040 - does this work as expected?
