This might be required because the device does not have any physical user input, or simply - * just to streamline the device upgrade process on the host PC. - * - * The following C code snippets may be used to enter the bootloader upon request by the user application. - * By using the watchdog to physically reset the controller, it is ensured that all system hardware is - * completely reset to their defaults before the bootloader is run. This is important; since bootloaders - * are written to occupy a very limited space, they usually make assumptions about the register states based - * on the default values after a hard-reset of the chip. - * - * \section Sec_SoftareBootAVR8 AVR8 Architecture - * The following software bootloader jump code is written for the AVR8 architecture. - * - * \code - * #include - * #include - * #include - * - * #include - * #include - * - * uint32_t Boot_Key ATTR_NO_INIT; - * - * #define MAGIC_BOOT_KEY 0xBADCAFE5 - * #define BOOTLOADER_START_ADDRESS ((FLASH_SIZE_BYTES - BOOTLOADER_SEC_SIZE_BYTES) >> 1) - * - * void Bootloader_Jump_Check(void) ATTR_INIT_SECTION(3); - * void Bootloader_Jump_Check(void) - * { - * // If the reset source was the bootloader and the key is correct, clear it and jump to the bootloader - * if ((MCUSR & (1 << WDRF)) && (Boot_Key == MAGIC_BOOT_KEY)) - * { - * Boot_Key = 0; - * ((void (*)(void))BOOTLOADER_START_ADDRESS)(); - * } - * } - * - * void Jump_To_Bootloader(void) - * { - * // If USB is used, detach from the bus and reset it - * USB_Disable(); - * - * // Disable all interrupts - * cli(); - * - * // Wait two seconds for the USB detachment to register on the host - * Delay_MS(2000); - * - * // Set the bootloader key to the magic value and force a reset - * Boot_Key = MAGIC_BOOT_KEY; - * wdt_enable(WDTO_250MS); - * for (;;); - * } - * \endcode - * - * Note that the bootloader magic key can be any arbitrary value.
