High-voltage
Programming
Figure 2-5. High-voltage (Parallel) Programming
To program the AVR using High-voltage (Parallel) Programming, connect the PROGC-
TRL to PORTD and PROGDATA to PORTB on the STK500 as shown in Figure 2-5.
Make sure that the TOSC-switch is placed in the XTAL position.
As described in the STK500 User Guide (jumper settings), mount the BSEL2 jumper in
order to High-voltage Program the ATmega devices. This setting also applies to High-
voltage Programming of the AVR.
The device can now be programmed using the High-voltage Programming mode in AVR
Studio STK500 software.
Note:
Note:
See the STK500 User Guide for information on how to use the STK500 front-
end software in High-voltage Programming mode.
For the High-voltage Programming mode to function correctly, the target voltage
must be higher than 4.5V.
