| 6 | * \brief AVR32 UC3 ISP trampoline. |
|---|
| 7 | * |
|---|
| 8 | * In order to be able to program a project with both BatchISP and JTAGICE mkII |
|---|
| 9 | * without having to take the general-purpose fuses into consideration, add this |
|---|
| 10 | * file to the project and change the program entry point to _trampoline. |
|---|
| 11 | * |
|---|
| 12 | * The pre-programmed ISP will be erased if JTAGICE mkII is used. |
|---|
| 13 | * |
|---|
| 14 | * - Compiler: GNU GCC for AVR32 |
|---|
| 15 | * - Supported devices: All AVR32UC devices can be used. |
