hi  to all ..
 OK so know i cant unlock the the flashon the MC9S12DP512, there was no problem when the squence  thats on page 1237 chapter 30 ran completly  everything was OK but. when i interrupted the sequence after only doing the MASS_ERASE, the 0xFF0F byte remained at 0xFF (the secured state). and now even if i run the complete sequence. It remains locked.. HELP!!
