IRQ SET params
Sets an interrupt flag in the PIO state machine. This is a PIO assembler instruction used within PIO programs to control interrupt signaling between state machines or to the main processor.
Parameters:
params: Interrupt number and optional modifiers (0-7 for PIO interrupts)
Context: Used in PIO assembler programs to set interrupt flags. PIO interrupts can be used for synchronization between multiple state machines or to signal the main processor.
Cross-reference: See F_the_pio_programming_package.md for PIO programming details and using_the_io_pins.md for general interrupt concepts.
