* \brief AVR32 UC3 ISP trampoline.
|
| 5 |
|
|
*
|
| 6 |
|
|
* In order to be able to program a project with both BatchISP and JTAGICE mkII
|
| 7 |
|
|
* without having to take the general-purpose fuses into consideration, add this
|
| 8 |
|
|
* file to the project and change the program entry point to __trampoline.
|
| 9 |
|
|
*
|
| 10 |
|
|
* The pre-programmed ISP will be erased if JTAGICE mkII is used.
|
| 11 |
|
|
*
|
| 12 |
|
|
* - Compiler: IAR EWAVR32
|
| 13 |
|
|
* - Supported devices: All AVR32UC devices can be used.
