There is also an DFU bootloader that resides in the upper 8Kb of FLASH
(unless you ERASE the flash with with ICE). You can enter this bootloader
(if it is in FLASH) by:
Holding both the SW1 (RESET) and SW2, then releasing SW1 while continuing
to hold SW2. SW2 connects to the PE2/HWB signal and causes a reset into
the bootloader memory region.
Then you can use FLIP to load code into FLASH (available at the Atmel Web
Site). The DFU USB driver for the DFU bootload is available in the usb
subdirectory in the FLIP installation location.
