    Question: Can you read out an M8 OTP once it's programmed?  Assuming the answer is YES  how do I prevent this?

     

    Answer:

    On the Hi-Lo programmer GUI (Cystart.exe), there is a "Security" button. Once this fuse is blown, the code will be protected. When it is read, only FFh's are shown.
