25.3.2.1 Memory regions, types and attributes
The processor reserves regions of the Private peripheral bus (PPB) address range for
core peripheral registers, see
The memory map is split 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.
Device — The processor preserves transaction order relative to other transactions to
Device or Strongly-ordered memory.
