Peripheral Frame 1 and Peripheral Frame 2 are grouped together so as to enable these blocks to be
write/read peripheral block protected. The protected mode ensures that all accesses to these blocks
happen as written. Because of the C28x pipeline, a write immediately followed by a read, to different
memory locations, will appear in reverse order on the memory bus of the CPU. This can cause problems
in certain peripheral applications where the user expected the write to occur first (as written). The C28x
CPU supports a block protection mode where a region of memory can be protected so as to make sure
that operations occur as written (the penalty is extra cycles are added to align the operations). This mode
is programmable and by default, it will protect the selected zones.
The wait-states for the various spaces in the memory map area are listed in
