Struct Scr 

#[repr(transparent)]
pub struct Scr(pub u32);

The SCR controls features of entry to and exit from low-power state.

0: u32

Implementations

impl Scr

pub const fn sleeponexit(&self) -> bool

Indicates sleep-on-exit when returning from Handler mode to Thread mode. Setting this bit to 1 enables an interrupt driven application to avoid returning to an empty main application. This bit is banked between Security states.

pub const fn set_sleeponexit(&mut self, val: bool)

Indicates sleep-on-exit when returning from Handler mode to Thread mode. Setting this bit to 1 enables an interrupt driven application to avoid returning to an empty main application. This bit is banked between Security states.

pub const fn sleepdeep(&self) -> Sleepdeep

Controls whether the processor uses sleep or deep sleep as its low-power mode. This bit is not banked between Security states.

pub const fn set_sleepdeep(&mut self, val: Sleepdeep)

Controls whether the processor uses sleep or deep sleep as its low-power mode. This bit is not banked between Security states.

pub const fn sleepdeeps(&self) -> Sleepdeeps

Controls whether the SLEEPDEEP bit is only accessible from the Secure state. This bit in only accessible from the Secure state, and behaves as RAZ/WI when accessed from the Nonsecure state. This bit is not banked between Security states.

pub const fn set_sleepdeeps(&mut self, val: Sleepdeeps)

Controls whether the SLEEPDEEP bit is only accessible from the Secure state. This bit in only accessible from the Secure state, and behaves as RAZ/WI when accessed from the Nonsecure state. This bit is not banked between Security states.

pub const fn sevonpend(&self) -> Sevonpend

Send Event on Pending bit. When an event or interrupt enters pending state, the event signal wakes up the processor from WFE. If the processor is not waiting for an event, the event is registered and affects the next WFE. The processor also wakes up on execution of an SEV instruction or an external event. This bit is banked between Security states.

pub const fn set_sevonpend(&mut self, val: Sevonpend)

Send Event on Pending bit. When an event or interrupt enters pending state, the event signal wakes up the processor from WFE. If the processor is not waiting for an event, the event is registered and affects the next WFE. The processor also wakes up on execution of an SEV instruction or an external event. This bit is banked between Security states.

Trait Implementations

impl Clone for Scr

fn clone(&self) -> Scr

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Scr

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Scr

fn default() -> Scr

Returns the “default value” for a type.

impl PartialEq for Scr

fn eq(&self, other: &Scr) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
