Instruction access disable bit:
0 = instruction fetches enabled
1 = instruction fetches disabled.

Shareable bit, see
• SRD
Subregion disable bits. For each bit in this field:
0 = corresponding sub-region is enabled
1 = corresponding sub-region is disabled
See
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
Specifies the size of the MPU protection region. The minimum permitted value is 3 (b00010), see See

The RASR defines the region size and memory attributes of the MPU region specified by the
RNR, and enables that region and any subregions. See the register summary in
page 213
RASR is accessible using word or halfword accesses:
The bit assignments are:
• the most significant halfword holds the region attributes
• the least significant halfword holds the region size and the region and subregion enable bits.
