Struct rp2040_pac::pio0::irq::IRQ_SPEC

pub struct IRQ_SPEC;

State machine IRQ flags register. Write 1 to clear. There are 8 state machine IRQ flags, which can be set, cleared, and waited on by the state machines. There’s no fixed association between flags and state machines – any state machine can use any flag.

Any of the 8 flags can be used for timing synchronisation between state machines, using IRQ and WAIT instructions. The lower four of these flags are also routed out to system-level interrupt requests, alongside FIFO status interrupts – see e.g. IRQ0_INTE.

You can read this register and get irq::R. You can reset, write, write_with_zero this register using irq::W. You can also modify this register. See API.

Trait Implementations

impl RegisterSpec for IRQ_SPEC

type Ux = u32

Raw register type (u8, u16, u32, …).

impl Resettable for IRQ_SPEC

reset() method sets IRQ to value 0

const RESET_VALUE: u32 = 0u32

Reset value of the register.

fn reset_value() -> Self::Ux

Reset value of the register.

impl Writable for IRQ_SPEC

write(|w| ..) method takes irq::W writer structure

const ZERO_TO_MODIFY_FIELDS_BITMAP: u32 = 0u32

Specifies the register bits that are not changed if you pass 1 and are changed if you pass 0

const ONE_TO_MODIFY_FIELDS_BITMAP: u32 = 255u32

Specifies the register bits that are not changed if you pass 0 and are changed if you pass 1

impl Readable for IRQ_SPEC

read() method returns irq::R reader structure
