I have a Willem 3. I have been reading a little bit more and I think i will not be able to do this, i read somewhere that the BLJB value can be modified only in paralell programming mode. Again, thanks a lot. Other than that, I have a At89c51rd2 datasheet guess I will dataaheet to meet the hardware conditions if I want to do this. It is very helpfull. How do I set these values?
