12.11.1.5 Subregions

Regions of 256 bytes or more are divided into eight equal-sized subregions. Set the corresponding bit in the SRD field of

the MPU_RASR field to disable a subregion. See

“MPU Region Attribute and Size Register”

. The least significant bit of

SRD controls the first subregion, and the most significant bit controls the last subregion. Disabling a subregion means

another region overlapping the disabled range matches instead. If no other enabled region overlaps the disabled

subregion, the MPU issues a fault.

Regions of 32, 64, and 128 bytes do not support subregions. With regions of these sizes, the SRD field must be set to

0x00, otherwise the MPU behavior is unpredictable.

12.11.1.6 Example of SRD Use

Two regions with the same base address overlap. Region 1 is 128 kB, and region 2 is 512 kB. To ensure the attributes

from region 1 apply to the first 128 kB region, set the SRD field for region 2 to b00000011 to disable the first two

subregions, as in

Figure 12-13

12.11.1.7 MPU Design Hints And Tips

To avoid unexpected behavior, disable the interrupts before updating the attributes of a region that the interrupt handlers

might access.

Ensure the software uses aligned accesses of the correct size to access MPU registers:

Except for the MPU_RASR, it must use aligned word accesses.

For the MPU_RASR, it can use byte or aligned halfword or word accesses.

The processor does not support unaligned accesses to MPU registers.

When setting up the MPU, and if the MPU has previously been programmed, disable unused regions to prevent any

previous region settings from affecting the new MPU setup.

MPU Configuration for a Microcontroller

Usually, a microcontroller system has only a single processor and no caches. In such a system, program the MPU as

In most microcontroller implementations, the shareability and cache policy attributes do not affect the system behavior.

However, using these settings for the MPU regions can make the application code more portable. The values given are

for typical situations. In special systems, such as multiprocessor designs or designs with a separate DMA engine, the

shareability attribute might be important. In these cases, refer to the recommendations of the memory device

manufacturer.
