The regions for SRAM and peripherals include bit-band regions. Bit-banding provides atomic operations
to bit data, see Section 2.2.5 (p. 18) .
The processor reserves regions of the Private peripheral bus (PPB) address range for core peripheral
registers, see Section 4.1 (p. 88) .
2.2.1 Memory regions, types and attributes
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:
Normal
The processor can re-order transactions for efficiency, or perform speculative
reads.
