* This bootloader enumerates to the host as a DFU Class device, allowing for DFU-compatible programming
* software to load firmware onto the AVR.
*
* This bootloader is compatible with Atmel's FLIP application. However, it requires the use of Atmel's
* DFU drivers. You will need to install Atmel's DFU drivers prior to using this bootloader. If you are
* using a 64 bit Windows OS, you will need to either disable the driver signing requirement (see online
* tutorials for details) or use a digitally signed version of the official Atmel driver provided by a
* third party AVR user at
* <a>http://www.avrfreaks.net/index.php?module=Freaks%20Academy&func=viewItem&item_id=2196&item_type=project</a>.
*
* As an open-source option, this bootloader is also compatible with the Linux Atmel USB DFU Programmer
* software, available for download at <a>http://sourceforge.net/projects/dfu-programmer/</a>.
*
* If SECURE_MODE is defined as true, upon start-up the bootloader will be locked, with only the chip erase
* function available (similar to Atmel's DFU bootloader). If SECURE_MODE is defined as false, all functions
* are usable on start-up without the prerequisite firmware erase.
*
* Out of the box this bootloader builds for the USB1287, and should fit into 4KB of bootloader space. If
* you wish to enlarge this space and/or change the AVR model, you will need to edit the BOOT_START and MCU
* values in the accompanying makefile.
*
* <b>NOTE:</b> This device spoofs Atmel's DFU Bootloader USB VID and PID so that the Atmel DFU bootloader
* drivers included with FLIP will work. If you do not wish to use Atmel's ID codes, please
* manually change them in Descriptors.c and alter your driver's INF file accordingly.
