Struct stm32f0xx_hal::pac::SCB

pub struct SCB { /* fields omitted */ }

System Control Block

Implementations

impl SCB

pub fn vect_active() -> VectActive

Returns the active exception number

impl SCB

pub fn set_sleepdeep(&mut self)

Set the SLEEPDEEP bit in the SCR register

pub fn clear_sleepdeep(&mut self)

Clear the SLEEPDEEP bit in the SCR register

impl SCB

pub fn set_sleeponexit(&mut self)

Set the SLEEPONEXIT bit in the SCR register

pub fn clear_sleeponexit(&mut self)

Clear the SLEEPONEXIT bit in the SCR register

impl SCB

pub fn sys_reset() -> !

Initiate a system reset request to reset the MCU

impl SCB

pub fn set_pendsv()

Set the PENDSVSET bit in the ICSR register which will pend the PendSV interrupt

pub fn is_pendsv_pending() -> bool

Check if PENDSVSET bit in the ICSR register is set meaning PendSV interrupt is pending

pub fn clear_pendsv()

Set the PENDSVCLR bit in the ICSR register which will clear a pending PendSV interrupt

pub fn set_pendst()

Set the PENDSTSET bit in the ICSR register which will pend a SysTick interrupt

pub fn is_pendst_pending() -> bool

Check if PENDSTSET bit in the ICSR register is set meaning SysTick interrupt is pending

pub fn clear_pendst()

Set the PENDSTCLR bit in the ICSR register which will clear a pending SysTick interrupt

impl SCB

pub fn get_priority(system_handler: SystemHandler) -> u8

Returns the hardware priority of system_handler

NOTE: Hardware priority does not exactly match logical priority levels. See NVIC.get_priority for more details.

pub unsafe fn set_priority(&mut self, system_handler: SystemHandler, prio: u8)

Sets the hardware priority of system_handler to prio

NOTE: Hardware priority does not exactly match logical priority levels. See NVIC.get_priority for more details.

On ARMv6-M, updating a system handler 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.

impl SCB

pub const PTR: *const RegisterBlock

Pointer to the register block

pub const fn ptr() -> *const RegisterBlock

Returns a pointer to the register block (to be deprecated in 0.7)

Trait Implementations

impl Deref for SCB

type Target = RegisterBlock

The resulting type after dereferencing.

pub fn deref(&self) -> &<SCB as Deref>::Target

Dereferences the value.
