WebMemory Protection Unit (MPU) is an optional component provided by the Cortex®-M7 core for memory protection. It divides the memory map into a number of regions with privilege permissions and access rules. This document provides information on how to configure memory regions using MPU provided by Microchip’s Cortex-M7 based MCUs. WebMemory Mapped IO or MMIO is the process of interacting with hardware devices by by reading from and writing to predefined memory addresses. All interactions with hardware on the Raspberry Pi occur using MMIO. A Peripheral is a hardware device with a specific address in memory that it writes data to and/or reads data from. All peripherals can be …

WebThe MPU divides the memory map into a number of regions, and defines the location, size, access permissions, and memory attributes of each region. It supports: independent attribute settings for each region overlapping regions export of memory attributes to the system. The memory attributes affect the behavior of memory accesses to the region.
