+ * \section Sec_Description Project Description:
+ *
+ * This bootloader enumerates to the host as a Mass Storage device, capable of reading and writing a new binary
+ * firmware image file, to load firmware onto the AVR.
+ *
+ * Out of the box this bootloader builds for the AT90USB1287 with an 8KB bootloader section size, and will fit
+ * into 8KB of bootloader space. If you wish to alter this size and/or change the AVR model, you will need to
+ * edit the MCU, FLASH_SIZE_KB and BOOT_SECTION_SIZE_KB values in the accompanying makefile.
+ *
+ * When the bootloader is running, the board's LED(s) will flash at regular intervals to distinguish the
+ * bootloader from the normal user application.
+ *
+ * \section Sec_Installation Driver Installation
+ *
+ * This bootloader uses the Mass Storage printer drivers inbuilt into all modern operating systems, thus no additional
+ * drivers need to be supplied for correct operation.
+ *
+ * \section Sec_HostApp Host Controller Application
+ *
+ * This bootloader is compatible with all operating systems that support the FAT12 file system format. To reprogram the
+ * device, overwrite a file stored on the virtual FAT filesystem with a new binary (BIN format) image. Remember to safely
+ * remove your device from the host using the host OS's ejection APIs, to ensure all data is correctly flushed to the
+ * bootloader's virtual filesystem and not cached in the OS's file system driver.
+ *
+ * The current device firmware can be read from the device by reading a file from the virtual FAT filesystem.
+ *
+ * \section Sec_API User Application API
+ *
+ * Several user application functions for FLASH and other special memory area manipulations are exposed by the bootloader,
+ * allowing the user application to call into the bootloader at runtime to read and write FLASH data.
+ *
+ * By default, the bootloader API jump table is located 32 bytes from the end of the device's FLASH memory, and follows the
+ * following layout:
+ *
+ * \code
+ * #define BOOTLOADER_API_TABLE_SIZE 32
+ * #define BOOTLOADER_API_TABLE_START ((FLASHEND + 1UL) - BOOTLOADER_API_TABLE_SIZE)
+ * #define BOOTLOADER_API_CALL(Index) (void*)((BOOTLOADER_API_TABLE_START + (Index * 2)) / 2)
+ *
+ * void (*BootloaderAPI_ErasePage)(uint32_t Address) = BOOTLOADER_API_CALL(0);
+ * void (*BootloaderAPI_WritePage)(uint32_t Address) = BOOTLOADER_API_CALL(1);
+ * void (*BootloaderAPI_FillWord)(uint32_t Address, uint16_t Word) = BOOTLOADER_API_CALL(2);
+ * uint8_t (*BootloaderAPI_ReadSignature)(uint16_t Address) = BOOTLOADER_API_CALL(3);
+ * uint8_t (*BootloaderAPI_ReadFuse)(uint16_t Address) = BOOTLOADER_API_CALL(4);
+ * uint8_t (*BootloaderAPI_ReadLock)(void) = BOOTLOADER_API_CALL(5);
+ * void (*BootloaderAPI_WriteLock)(uint8_t LockBits) = BOOTLOADER_API_CALL(6);
+ *
+ * #define BOOTLOADER_MAGIC_SIGNATURE_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 2))
+ * #define BOOTLOADER_MAGIC_SIGNATURE 0xDCFB
+ *
+ * #define BOOTLOADER_CLASS_SIGNATURE_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 4))
+ * #define BOOTLOADER_MASS_STORAGE_SIGNATURE 0xDF30
+ *
+ * #define BOOTLOADER_ADDRESS_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 8))
+ * #define BOOTLOADER_ADDRESS_LENGTH 4
+ * \endcode
+ *
+ * \subsection SSec_API_MemLayout Device Memory Map
+ * The following illustration indicates the final memory map of the device when loaded with the bootloader.
+ *

+ * +----------------------------+ FLASHEND
+ * \endverbatim
+ *
+ * Bootloaders reporting a device release revision number of 1.00 or greater are bootloader API enabled. From the application
+ * the API support of the bootloader can be detected by reading the FLASH memory bytes located at address \c BOOTLOADER_MAGIC_SIGNATURE_START
+ * and comparing them to the value \c BOOTLOADER_MAGIC_SIGNATURE. The class of bootloader can be determined by reading the
+ * FLASH memory bytes located at address \c BOOTLOADER_CLASS_SIGNATURE_START and comparing them to the value \c BOOTLOADER_MASS_STORAGE_SIGNATURE.
+ * The start address of the bootloader can be retrieved by reading the bytes of FLASH memory starting from address \c BOOTLOADER_ADDRESS_START.
+ *
+ * \section Sec_Options Project Options
