1.4 Memory Mapping

Figure 5 shows the various memory configurations of the STR73xF system. The system

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 Figure 5) are protected from access 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.
