Behavior of memory accesses
Additional memory access constraints for shared memory
< Means that accesses are observed in program order, that is, A1 is always observed before A2.
The behavior of accesses to each region in the memory map is:
Table 10-4.
1.
The Code, SRAM, and external RAM regions can hold programs. However, ARM recommends
that programs always use the Code region. This is because the processor has separate buses
that enable instruction fetches and data accesses to occur simultaneously.
When a system includes shared memory, some memory regions have additional access con-
straints, and some regions are subdivided, as
Table 10-5.
