The MPU_RASR defines the region size and memory attributes of the MPU region specified by the MPU_RNR, and
enables that region and any subregions.
MPU_RASR is accessible using word or halfword accesses:
• XN: Instruction Access Disable
0: Instruction fetches enabled.
1: Instruction fetches disabled.
• AP: Access Permission
See
• TEX, C, B: Memory Access Attributes
See
• S: Shareable
See
• SRD: Subregion Disable
For each bit in this field:
0: corresponding sub-region is enabled.
1: corresponding sub-region is disabled.

Region sizes of 128 bytes and less do not support subregions. When writing the attributes for such a region, write the SRD
field as 0x00.
• SIZE: Size of the MPU Protection Region
The minimum permitted value is 3 (b00010).
