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
STK526.
AT90USB82/162 part comes with a default factory pre-programmed USB bootloader
located in the on-chip boot section of the AT90USB82/162. This is the easiest and
fastest way to reprogram the device directly over the USB interface. The “Flip” PC-
based application offers a flexible and user friendly interface to reprogram the
application over the USB bus.
The HWB pin of the AT90USB82/162 allows to force the bootloader execution after
reset. (Please refer to AT90USB82/162 datasheet section “Bootloader support”). To
force bootloader execution, operate as follows:
“STKX1” and ”STKX2” jumpers should be closed
Press both “RST” and “HWB” push buttons
First release the “RST” push button
Then release the “HWB” push button
