Application Section
Application Table section
All AVR instructions are 16 or 32 bits wide, and each Flash location is 16 bits wide. The Flash
memory in XMEGA is organized in two main sections, the Application Section and the Boot
Loader section, as shown in
but device dependent. These two sections have separate lock bits and can have different level
of protection. The Store Program Memory (SPM) instruction used to write to the Flash from the
application software, will only operate when executed from the Boot Loader Section.
The Application Section contains an Application Table Section with separate lock settings. This
can be used for safe storage of Non-volatile data in the Program Memory.
Figure 4-1.
The Application section is the section of the Flash that is used for storing the executable applica-
tion code. The protection level for the Application section can be selected by the Boot Lock Bits
for this section. The Application section can not store any Boot Loader code since the SPM
instruction cannot be executed from the Application section.
The Application Table section is a part of the Application Section of the Flash that can be used
for storing data. The size is identical to the Boot Loader Section. The protection level for the
Application Table section can be selected by the Boot Lock Bits for this section. The possibilities
