[]Struct metro_m0::NVIC

pub struct NVIC { /* fields omitted */ }

Nested Vector Interrupt Controller

Methods

impl NVIC

pub fn clear_pending<I>(&mut self, interrupt: I) where
    I: Nr, 

Deprecated since 0.5.8:

Use NVIC::unpend

Clears interrupt's pending state

pub fn disable<I>(&mut self, interrupt: I) where
    I: Nr, 

Disables interrupt

pub fn enable<I>(&mut self, interrupt: I) where
    I: Nr, 

Enables interrupt

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_enabled<I>(interrupt: I) -> bool where
    I: Nr, 

Checks if interrupt is enabled

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, 

Forces interrupt into pending state

pub fn set_pending<I>(&mut self, interrupt: I) where
    I: Nr, 

Deprecated since 0.5.8:

Use NVIC::pend

Forces interrupt into pending state

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, 

Clears interrupt's pending state

impl NVIC

pub fn ptr() -> *const RegisterBlock

Returns a pointer to the register block
