Memory regions, types and attributes
This section describes the processor memory map, the behavior of memory accesses, and the
bit-banding features. The processor has a fixed memory map that provides up to 4GB of
addressable memory. The memory map is:
The regions for SRAM and peripherals include bit-band regions. Bit-banding provides atomic
operations to bit data, see
The processor reserves regions of the Private peripheral bus (PPB) address range for core
peripheral registers, see
This memory mapping is generic to ARM Cortex-M3 products. To get the specific memory map-
ping of this product, refer to the Memories section of the datasheet.
The memory map and the programming of the MPU split the memory map into regions. Each
region has a defined memory type, and some regions have additional memory attributes. The
memory type and attributes determine the behavior of accesses to the region.
The memory types are:
