Boot Loader Features
Application and Boot Loader Flash Sections
Application Section
BLS – Boot Loader Section
In Atmel
Self-Programming mechanism for downloading and uploading program code by the MCU
itself. This feature allows flexible application software updates controlled by the MCU using a
Flash-resident Boot Loader program. The Boot Loader program can use any available data
interface and associated protocol to read code and write (program) that code into the Flash
memory, or read the code from the program memory. The program code within the Boot
Loader section has the capability to write into the entire Flash, including the Boot Loader
memory. The Boot Loader can thus even modify itself, and it can also erase itself from the
code if the feature is not needed anymore. The size of the Boot Loader memory is configu-
rable with fuses and the Boot Loader has two separate sets of Boot Lock bits which can be set
independently. This gives the user a unique flexibility to select different levels of protection.

Note:
The Flash memory is organized in two main sections, the Application section and the Boot
Loader section (see
by the BOOTSZ Fuses as shown in
These two sections can have different level of protection since they have different sets of Lock
bits.
The Application section is the section of the Flash that is used for storing the application code.
The protection level for the Application section can be selected by the application Boot Lock
bits (Boot Lock bits 0), see
any Boot Loader code since the SPM instruction is disabled when executed from the Applica-
tion section.
While the Application section is used for storing the application code, the The Boot Loader
software must be located in the BLS since the SPM instruction can initiate a programming
when executing from the BLS only. The SPM instruction can access the entire Flash, including
the BLS itself. The protection level for the Boot Loader section can be selected by the Boot
Loader Lock bits (Boot Lock bits 1), see
