Struct Clic

pub struct Clic { /* private fields */ }

Implementations

impl Clic

pub const fn new(in_use_interrupts: u64) -> Clic

pub fn clear_all_pending(&self)

Clear all pending interrupts.

pub fn enable_all(&self)

Enable ONLY the interrupts we actually want to use.

The CLIC allows disabled interrupts to still set the pending bit. Therefore we have to be very careful about which interrupts we check.

pub fn disable_pending(&self)

pub fn disable_all(&self)

Disable all interrupts.

pub fn next_pending(&self) -> Option<u32>

Get the index (0-256) of the lowest number pending interrupt, or None if none is pending.

pub fn complete(&self, index: u32)

Signal that an interrupt is finished being handled. In Tock, this should be called from the normal main loop (not the interrupt handler). This marks the interrupt as no longer pending and re-enables it.

pub fn has_pending(&self) -> bool

Return true if there are any pending interrupts in the CLIC, false otherwise.
