The Cortex-M3 MPU memory map is unified. This means instruction accesses and data accesses have
same region settings.
If a program accesses a memory location that is prohibited by the MPU, the processor generates a
memory management fault. This causes a fault exception, and might cause termination of the process
in an OS environment. In an OS environment, the kernel can update the MPU region setting dynamically
based on the process to be executed. Typically, an embedded OS uses the MPU for memory protection.
Configuration of MPU regions is based on memory types, see Section 2.2.1 (p. 15) .
Table 4.37 (p. 114) shows the possible MPU region attributes. Please not that the Shareability
and cache behavior attributes are usually not relevant for the EFM32 devices since these are not
used by other bus masters. However, these can be useful together with the DMA Controller. See
Section 4.5.9.1 (p. 123) for guidelines on using these attributes.

Description
Strongly-
ordered
-
All accesses to Strongly-ordered memory occur in program
order. All Strongly-ordered regions are assumed to be shared.
Device
Shared
-
Memory-mapped peripherals that several processors share.
Non-shared
-
Memory-mapped peripherals that only a single processor uses.
Normal
Shared
Non-cacheable Write-
through Cacheable Write-
back Cacheable
Normal memory that is shared between several processors.
Non-shared
Non-cacheable Write-
through Cacheable Write-
back Cacheable
Normal memory that only a single processor uses.
Use the MPU registers to define the MPU regions and their attributes. The MPU registers are:

4.5.1 MPU Type Register
The TYPE register indicates how many regions the MPU supports. See the register summary in
Table 4.38 (p. 114) for its attributes. The bit assignments are:
