Implementations§

impl R

source

pub fn enable(&self) -> ENABLE_R

Bit 0 - Enables the region.

source

pub fn size(&self) -> SIZE_R

Bits 1:5 - Indicates the region size. Region size in bytes = 2^(SIZE+1). The minimum permitted value is 7 (b00111) = 256Bytes

source

pub fn srd(&self) -> SRD_R

Bits 8:15 - Subregion Disable. For regions of 256 bytes or larger, each bit of this field controls whether one of the eight equal subregions is enabled.

source

pub fn attrs(&self) -> ATTRS_R

Bits 16:31 - The MPU Region Attribute field. Use to define the region attribute control.
28 = XN: Instruction access disable bit:
0 = Instruction fetches enabled.
1 = Instruction fetches disabled.
26:24 = AP: Access permission field
18 = S: Shareable bit
17 = C: Cacheable bit
16 = B: Bufferable bit
