Access:
Reset:
The MPU_RNR selects which memory region is referenced by the MPU_RBAR and MPU_RASR registers.
• REGION
Indicates the MPU region referenced by the MPU_RBAR and MPU_RASR registers.
The MPU supports 8 memory regions, so the permitted values of this field are 0-7.
Normally, the required region number is written to this register before accessing the MPU_RBAR or MPU_RASR. However,
the region number can be changed by writing to the MPU_RBAR with the VALID bit set to 1; see
Address Register”
