7.6.3.3 Extending the Bootloader
An application can integrate its own bootloader by enlarging the bootloader protected area spec-
ified by the BOOTPROT general-purpose fuse bits (see Section 6.2.1). In this case, Atmel’s
bootloader will launch the application as usual at 80002000h where the applicative bootloader
should be located. The applicative bootloader is responsible for the following operations.
Once Atmel’s ISP has been used to program the application and its bootloader, it can be deacti-
vated by setting the ISP_IO_COND_EN general-purpose fuse bit to 0 (see Section 6.2.1) if it is
no longer needed.
