Background:
- I2S interrupt has high priority.
- When I2S ISR detects a specific condition, it should pend a suitable lower priority interrupt for further processing.
- The lower priority interrupt must not run before I2S ISR returns, and must also allow nesting of other higher priority interrupts.
On other processors, this would be solved using a software interrupt, but the intr(k5) instruction cannot be used since it executes the ISR directly, despite a higher priority is still running.
Is there some way to just set an interrupt pending?
