Entering the Boot Loader Program
Entering the Boot Loader takes place by a jump or call from the application program. This may
be initiated by a trigger such as a command received via the TWI interface. Alternatively, the
Boot Reset Fuse can be programmed so that the Reset Vector is pointing to the Boot Flash start
address after a reset. In this case, the Boot Loader is started after a reset. After the application
code is loaded, the program can start executing the application code. Note that the fuses cannot
be changed by the MCU itself. This means that once the Boot Reset Fuse is programmed, the
Reset Vector will always point to the Boot Loader Reset and the fuse can only be changed
through the serial or parallel programming interface.
