Note:
The MPU_RBAR defines the base address of the MPU region selected by the MPU_RNR, and can update the value of the
MPU_RNR.
Write MPU_RBAR with the VALID bit set to 1 to change the current region number and update the MPU_RNR.
• ADDR: Region Base Address
The value of N depends on the region size. The ADDR field is bits[31:N] of the MPU_RBAR. The region size, as specified
by the SIZE field in the MPU_RASR, defines the value of N:
N = Log2(Region size in bytes),
If the region size is configured to 4 GB, in the MPU_RASR, there is no valid ADDR field. In this case, the region occupies
the complete memory map, and the base address is 0x00000000.
The base address is aligned to the size of the region. For example, a 64 KB region must be aligned on a multiple of 64 KB,
for example, at 0x00010000 or 0x00020000.
• VALID: MPU Region Number Valid
Write:
0: MPU_RNR not changed, and the processor updates the base address for the region specified in the MPU_RNR, and
ignores the value of the REGION field.
1: the processor updates the value of the MPU_RNR to the value of the REGION field, and updates the base address for
the region specified in the REGION field.
Always reads as zero.
• REGION: MPU Region
For the behavior on writes, see the description of the VALID field.
On reads, returns the current region number, as specified by the MPU_RNR.

If the region size is 32B, the ADDR field is bits [31:5] and there is no Reserved field.
