Memory protection unit

The STM32W108 includes the ARM® Cortex-M3 Memory Protection Unit, or MPU. The

MPU controls access rights and characteristics of up to eight address regions, each of

which may be divided into eight equal sub-regions. Refer to the ARM® Cortex-M3 Technical

Reference Manual (DDI 0337A) for a detailed description of the MPU.

ST software configures the MPU in a standard configuration and application software should

not modify it. The configuration is designed for optimal detection of illegal instruction or data

accesses. If an illegal access is attempted, the MPU captures information about the access

type, the address being accessed, and the location of the offending software. This simplifies

software debugging and increases the reliability of deployed devices. As a consequence of

this MPU configuration, accessing RAM and register bit-band address alias regions is not

permitted, and generates a bus fault if attempted.
