The Prog Data signals are used for the data bus when parallel High-voltage Program-
ming an AVR device. During ISP programming, DATA5 is used as MOSI, DATA6 is
used as MISO, and DATA7 is used for SCK.
Note:
STK500 has 2 push buttons and 3 LEDs for special functions and status indication. The
following section explains these features. Figure 3-38 shows the placement of these
functions.

The RESET push button resets the target AVR device when pushed. The master micro-
controller is not controlled by the RESET push button. When the RESET jumper is not
mounted, the RESET push button is disabled.
All Prog Data signals are based on 5V CMOS logic. No voltage conversion to
adapt to VTG is done on these signals.
