pub struct SAU { /* private fields */ }

Security Attribution Unit

Implementations

impl SAU

pub fn region_numbers(&self) -> u8

Get the number of implemented SAU regions.

pub fn enable(&mut self)

Enable the SAU.

pub fn set_region(
    &mut self,
    region_number: u8,
    region: SauRegion
) -> Result<(), SauError>

Set a SAU region to a region number. SAU regions must be 32 bytes aligned and their sizes must be a multiple of 32 bytes. It means that the 5 least significant bits of the base address of a SAU region must be set to zero and the 5 least significant bits of the limit address must be set to one. The region number must be valid. This function is executed under a critical section to prevent having inconsistent results.

pub fn get_region(&mut self, region_number: u8) -> Result<SauRegion, SauError>

Get a region from the SAU. The region number must be valid. This function is executed under a critical section to prevent having inconsistent results.

impl SAU

pub const PTR: *const RegisterBlock = {0xe000edd0 as *const peripheral::sau::RegisterBlock}

Pointer to the register block

pub const fn ptr() -> *const RegisterBlock

👎Deprecated since 0.7.5: Use the associated constant PTR instead

Returns a pointer to the register block

Trait Implementations

impl Deref for SAU

type Target = RegisterBlock

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
