* \brief AVR32 UC3 ISP trampoline.
*
* In order to be able to program a project with both BatchISP and JTAGICE mkII
* without having to take the general-purpose fuses into consideration, add this
* file to the project and change the program entry point to __trampoline.
*
* The pre-programmed ISP will be erased if JTAGICE mkII is used.
