Re: ds89c450 locked

don't waste your time ..
you can't touch them ..
you can re-program the whole thing but as far as the lock bits are concerned, once locked you can just kiss them goodbye ..

cheers,

really...

I read in the user guide, that the lock bits can be cleared with a mass erase.

I was hoping somene would be able to tell me how to perform a mass erase.

I found the solution.
Type "K" commands (K+ENTER) in MTK and the controller ready to reprogramm.
