Nested Vector Interrupt Controller
Methods
impl NVIC
[src]
impl NVIC
pub fn request<I>(&mut self, interrupt: I) where
I: Nr,
[src]
pub fn request<I>(&mut self, interrupt: I) where
I: Nr,
Request an IRQ in software
Writing a value to the INTID field is the same as manually pending an interrupt by setting
the corresponding interrupt bit in an Interrupt Set Pending Register. This is similar to
set_pending
.
This method is not available on ARMv6-M chips.
pub fn clear_pending<I>(&mut self, interrupt: I) where
I: Nr,
[src]
pub fn clear_pending<I>(&mut self, interrupt: I) where
I: Nr,
: Use NVIC::unpend
Clears interrupt
's pending state
pub fn mask<I>(interrupt: I) where
I: Nr,
[src]
pub fn mask<I>(interrupt: I) where
I: Nr,
Disables interrupt
pub unsafe fn unmask<I>(interrupt: I) where
I: Nr,
[src]
pub unsafe fn unmask<I>(interrupt: I) where
I: Nr,
Enables interrupt
This function is unsafe
because it can break mask-based critical sections
pub fn disable<I>(&mut self, interrupt: I) where
I: Nr,
[src]
pub fn disable<I>(&mut self, interrupt: I) where
I: Nr,
: Use NVIC::mask
Disables interrupt
pub fn enable<I>(&mut self, interrupt: I) where
I: Nr,
[src]
pub fn enable<I>(&mut self, interrupt: I) where
I: Nr,
: Use NVIC::unmask
WARNING This method is a soundness hole in the API; it should actually be an unsafe
function. Use NVIC::unmask
which has the right unsafety.
pub fn get_priority<I>(interrupt: I) -> u8 where
I: Nr,
[src]
pub fn get_priority<I>(interrupt: I) -> u8 where
I: Nr,
Returns the NVIC priority of interrupt
NOTE NVIC encodes priority in the highest bits of a byte so values like 1
and 2
map
to the same priority. Also for NVIC priorities, a lower value (e.g. 16
) has higher
priority (urgency) than a larger value (e.g. 32
).
pub fn is_active<I>(interrupt: I) -> bool where
I: Nr,
[src]
pub fn is_active<I>(interrupt: I) -> bool where
I: Nr,
Is interrupt
active or pre-empted and stacked
pub fn is_enabled<I>(interrupt: I) -> bool where
I: Nr,
[src]
pub fn is_enabled<I>(interrupt: I) -> bool where
I: Nr,
Checks if interrupt
is enabled
pub fn is_pending<I>(interrupt: I) -> bool where
I: Nr,
[src]
pub fn is_pending<I>(interrupt: I) -> bool where
I: Nr,
Checks if interrupt
is pending
pub fn pend<I>(interrupt: I) where
I: Nr,
[src]
pub fn pend<I>(interrupt: I) where
I: Nr,
Forces interrupt
into pending state
pub fn set_pending<I>(&mut self, interrupt: I) where
I: Nr,
[src]
pub fn set_pending<I>(&mut self, interrupt: I) where
I: Nr,
: Use NVIC::pend
Forces interrupt
into pending state
pub unsafe fn set_priority<I>(&mut self, interrupt: I, prio: u8) where
I: Nr,
[src]
pub unsafe fn set_priority<I>(&mut self, interrupt: I, prio: u8) where
I: Nr,
Sets the "priority" of interrupt
to prio
NOTE See get_priority
method for an explanation
of how NVIC priorities work.
On ARMv6-M, updating an interrupt priority requires a read-modify-write operation. On ARMv7-M, the operation is performed in a single atomic write operation.
Unsafety
Changing priority levels can break priority-based critical sections (see
register::basepri
) and compromise memory safety.
pub fn unpend<I>(interrupt: I) where
I: Nr,
[src]
pub fn unpend<I>(interrupt: I) where
I: Nr,
Clears interrupt
