IRQ WAIT params
Waits for an interrupt flag to be set in the PIO state machine. This instruction stalls the state machine until the specified interrupt condition is met.
Parameters:
params: Interrupt number to wait for (0-7 for PIO interrupts)
Context: Used in PIO assembler programs to synchronize state machine execution with interrupt events. The state machine will pause until the specified interrupt flag is set.
Cross-reference: See F_the_pio_programming_package.md for PIO programming details and using_the_io_pins.md for general interrupt concepts.
