The bootloader manages the USB communication protocol and performs read/write operations
from/to the on-chip memories.
The bootloader is located at the beginning of the on-chip flash array where an area of up to 64
kB can be configured to be write-protected by the internal flash controller. The bootloader pro-
tected size must be at least the size of the bootloader. On AVR UC3, it is configured to 8 kB.

BatchISP is the PC tool that allows to program a part using the AVR UC3 USB DFU bootloader.
It is compatible with Windows and Linux. It is integrated into AVR32Studio thanks to a plugin.
Note that all GCC make files of the UC3 software framework have programming goals using
BatchISP.
