The AVR clock frequency (external) coming from STK500 (XT1/XT2) can also be
controlled from AVR Studio®.
The AVR RESET coming from STK500 (NRST - EXP.CON 0) can also control the
STK525. STK525 is protected against +12V RESET pulse (parallel programing not
allowed for AT90USBxxx on STK525) coming from STK500.
AT90USBxxx part comes with a default factory pre-programmed USB bootloader
located in the on-chip boot section of the AT90USBxxx. This is the easiest and fastest
way to reprogram the device directly over the USB interface. The “Flip” PC side
application available for free on Atmel website offers a flexible and user friendly
interface to reprogram the application over the USB bus.
“STKX1” and ”STKX2” jumpers should be closed
