+ *  \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_START(Index)        (void*)(((FLASHEND - 32) + (2 * Index)) / 2)
+ *  void    (*BootloaderAPI_ErasePage)(uint32_t Address)               = BOOTLOADER_API_START(0);
+ *  void    (*BootloaderAPI_WritePage)(uint32_t Address)               = BOOTLOADER_API_START(1);
+ *  void    (*BootloaderAPI_FillWord)(uint32_t Address, uint16_t Word) = BOOTLOADER_API_START(2);
+ *  uint8_t (*BootloaderAPI_ReadSignature)(uint16_t Address)           = BOOTLOADER_API_START(3);
+ *  uint8_t (*BootloaderAPI_ReadFuse)(uint16_t Address)                = BOOTLOADER_API_START(4);
+ *  uint8_t (*BootloaderAPI_ReadLock)(void)                            = BOOTLOADER_API_START(5);
+ *  void    (*BootloaderAPI_WriteLock)(uint8_t LockBits)               = BOOTLOADER_API_START(6);
+ *
+ *  #define BOOTLOADER_SIG_START               (FLASHEND - 32)
+ *  #define BOOTLOADER_SIGNATURE               0xDCFB
+ *  \endcode
+ *
+ *  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_SIG_START
+ *  and comparing them to the value \c BOOTLOADER_SIGNATURE.
+ *
