+ * \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.
+ *
+ * - Compiler:           GNU GCC for AVR32
+ * - Supported devices:  All AVR32UC devices can be used.
+ *
