6.1 Memory layout part with the preprogrammed boot loader resets as any other part, at Atmel AVR UC3 80000000h. Boot loader execution begins here. The boot loader first performs the boot process to know whether it should start the USB DFU ISP or the application. If the tested conditions indi- cate that the USB DFU ISP should be started, then execution continues in the boot loader area between 80000000h and 80002000h;... - Page 6 AVR UC3 devices are shipped with their fuses set as follows: • For Atmel AVR UC3 C series: The general purpose fuses are set to F877FFFFh • That is, BOD is enabled, and the boot loader area is set to 8192 bytes.
