Struct MpuCtrl

#[repr(transparent)]
pub struct MpuCtrl(pub u32);

Control register for DMA MPU. Accessible only from a Privileged context.

Tuple Fields

0: u32

Implementations

impl MpuCtrl

pub const fn p(&self) -> bool

Determine whether an address not covered by an active MPU region is Privileged (1) or Unprivileged (0)

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

Determine whether an address not covered by an active MPU region is Privileged (1) or Unprivileged (0)

pub const fn s(&self) -> bool

Determine whether an address not covered by an active MPU region is Secure (1) or Non-secure (0)

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

Determine whether an address not covered by an active MPU region is Secure (1) or Non-secure (0)

pub const fn ns_hide_addr(&self) -> bool

By default, when a region’s S bit is clear, Non-secure-Privileged reads can see the region’s base address and limit address. Set this bit to make the addresses appear as 0 to Non-secure reads, even when the region is Non-secure, to avoid leaking information about the processor SAU map.

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

By default, when a region’s S bit is clear, Non-secure-Privileged reads can see the region’s base address and limit address. Set this bit to make the addresses appear as 0 to Non-secure reads, even when the region is Non-secure, to avoid leaking information about the processor SAU map.

Trait Implementations

impl Clone for MpuCtrl

fn clone(&self) -> MpuCtrl

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MpuCtrl

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

Formats the value using the given formatter.

impl Default for MpuCtrl

fn default() -> MpuCtrl

Returns the “default value” for a type.

impl PartialEq for MpuCtrl

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