NOTE
When the code-security passwords are programmed, all addresses between
0x3F7F80 and 0x3F7FF5 cannot be used as program code or data. These locations
must be programmed to 0x0000.
If the code security feature is not used, addresses 0x3F7F80 through 0x3F7FEF may
be used for code or data. Addresses 0x3F7FF0 – 0x3F7FF5 are reserved for data and
should not contain program code. .
On ROM devices, addresses 0x3F7FF0 – 0x3F7FF5 and 0x3D7BFC – 0x3D7BFF are
reserved for TI, irrespective of whether code security has been used or not. User
application should not use these locations in any way.
Table 3-5
shows how to handle these memory locations.

Application code and data
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
Table 3-6
