Memory mapping
Figure 5
memory map (from 0x0000_0000 to 0xFFFF_FFFF) is shown on the left part of the figure,
the right part shows maps of the Flash and APB areas. For flexibility the Flash or RAM
addresses can be aliased to Block 0 addresses using the remapping feature
Most reserved memory spaces (gray shaded areas in
by the user code. When an access this memory space is attempted, an ABORT signal is
generated. Depending on the type of access, the ARM processor will enter “prefetch abort”
state (Exception vector 0x0000_000C) or “data abort” state (Exception vector
0x0000_0010). It is up to the application software to manage these abort exceptions.
