Struct Mpu

pub struct Mpu(/* private fields */);

Wrapper around the Cortex-M4 Memory Protection Unit (MPU).

Implementations

impl Mpu

pub const MIN_REGION_SIZE: Size = Size::S32B

The smallest supported region size.

pub const REGION_COUNT: u8 = 8u8

Number of supported memory regions.

pub unsafe fn new(raw: MPU) -> Self

Creates a new MPU wrapper, taking ownership of the MPU peripheral.

Safety

This is safe to call if the processor is a Cortex-M4 or M4F and has an MPU.

pub fn into_inner(self) -> MPU

Consumes self and returns the raw MPU peripheral.

pub fn configure_unprivileged(&mut self, regions: &ArrayVec<[Region; 8]>)

Configures the MPU to restrict access to software running in unprivileged mode.

Code running in privileged mode will not be restricted by the MPU.
