Implementations

impl Sleepctrl

pub const fn light_sleep(&self) -> bool

By default, any processor sleep will deassert the system-level clock request. Reenabling the clocks incurs 5 cycles of additional latency on wakeup. Setting LIGHT_SLEEP to 1 keeps the clock request asserted during a normal sleep (Arm SCR.SLEEPDEEP = 0), for faster wakeup. Processor deep sleep (Arm SCR.SLEEPDEEP = 1) is not affected, and will always deassert the system-level clock request.

pub fn set_light_sleep(&mut self, val: bool)

By default, any processor sleep will deassert the system-level clock request. Reenabling the clocks incurs 5 cycles of additional latency on wakeup. Setting LIGHT_SLEEP to 1 keeps the clock request asserted during a normal sleep (Arm SCR.SLEEPDEEP = 0), for faster wakeup. Processor deep sleep (Arm SCR.SLEEPDEEP = 1) is not affected, and will always deassert the system-level clock request.

pub const fn wicenreq(&self) -> bool

Request that the next processor deep sleep is a WIC sleep. After setting this bit, before sleeping, poll WICENACK to ensure the processor interrupt controller has acknowledged the change.

pub fn set_wicenreq(&mut self, val: bool)

Request that the next processor deep sleep is a WIC sleep. After setting this bit, before sleeping, poll WICENACK to ensure the processor interrupt controller has acknowledged the change.

pub const fn wicenack(&self) -> bool

Status signal from the processor’s interrupt controller. Changes to WICENREQ are eventually reflected in WICENACK.

pub fn set_wicenack(&mut self, val: bool)

Status signal from the processor’s interrupt controller. Changes to WICENREQ are eventually reflected in WICENACK.

Trait Implementations

impl Clone for Sleepctrl

fn clone(&self) -> Sleepctrl

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Sleepctrl

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

Formats the value using the given formatter.

impl Default for Sleepctrl

fn default() -> Sleepctrl

Returns the “default value” for a type.

impl PartialEq for Sleepctrl

fn eq(&self, other: &Sleepctrl) -> 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.
