Project description

Chapter 32: W55MH32’s MPU - Memory Protection Unit The MPU (Memory Protection Unit) is a crucial module in the W55MH32 that is responsible for managing the access permissions and attributes of memory regions. It divides memory areas and sets access rules (such as read/write/execute permissions, cache policies), thereby enhancing the security and stability of the system. It is particularly suitable for multi-tasking systems (such as RTOS) or scenarios where critical resources need to be isolated. Overview of MPU Function Basic Concepts MPU is a hardware module built into the W55MH32. It does…
