Flash Program Memory
spaces can be locked for further write and read/write operations. This prevents unrestricted
access to the application software.
A separate memory section contains the Fuse bytes. These are used for setting important sys-
tem functions, and write access is only possible from an external programmer.
The XMEGA contains On-chip In-System Reprogrammable Flash memory for program storage.
The Flash memory can be accessed for read and write both from an external programmer
through the PDI, or from application software running in the CPU.
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.
