Hardware Description
AVR STK500 User Guide

1925C–AVR–3/03
Figure 3-25. RESET Jumper Options
The STK500 master microcontroller controls the RESET signal to the target AVR. The
RESET signal is accessible on the PORTE/AUX header; this pin can also be used for
external RESET signal. Figure 3-26 shows the internal connection of the RESET signal.
Figure 3-26. Internal RESET Connection
Note:
During High-voltage Programming, STK500 applies 12V to the AVR’s RESET
line. Thus, an external reset circuit not capable of handling this must be discon-
nected before High-voltage Programming the AVR.
