board accordingly.
Use Parallel Programming to
unprogram the RSTDISBL Fuse.
Please refer to Figure 2-5 for
correct Parallel Programming setup.
Please refer to the AT90PWM3 data
sheet for the Parallel Programming
Voltage limits. Adjust the target
voltage on the STK500 board
accordingly.
Connect the ISP cable according to
Figure 2-7.
Remove Reset Jumper on STK500
Board
Please set the DWEN bit using
parallel programming
