7.3.3. Overlapping regions

You can define overlapping memory protection regions. If several memory regions map the same memory, the PU uses the highest numbered region to control access to the memory.

Figure 7.1 shows an example of memory regions. In this example, a background region covers the whole address space. The foreground regions overlap the background region.

Instruction regions have corresponding data regions to allow for access to data contained in literal pools within code.
