addr: the address to clean
size: size of the memory block, in number of bytes
Cleans cache starting from the lowest 32-byte aligned address represented by addr,
in blocks of 32 bytes until at least size bytes have been cleaned.

sourcepub fn is_pendst_pending() -> bool
pub fn is_pendst_pending() -> bool
Check if PENDSTSET bit in the ICSR register is set meaning SysTick interrupt is pending
sourcepub fn clear_pendst()
pub fn clear_pendst()

sourceimpl SCB
impl SCB
sourcepub fn get_priority(system_handler: SystemHandler) -> u8
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.
sourcepub unsafe fn set_priority(&mut self, system_handler: SystemHandler, prio: u8)
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.
