I have tried within the CodeWarrior IDE to unsecure it, but I have not had any luck what so ever. I have found other forums which tell me I need to place the chip into "special single chip mode", but I am unable to find the "MODC" pin located on the board to do so. If anyone has any other form of help to mass erase this chip please send it my way. Thank you so very much for your time!!</P></BODY></HTML> Fri, 13 May 2011 03:09:10 GMT jonathan_abbati 2011-05-13T03:09:10Z Adapt9s12D  (MC9s12dg128) Unsecuring https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Adapt9s12D-MC9s12dg128-Unsecuring/m-p/205793#M8354 <HTML><HEAD></HEAD><BODY><P>Hello Friends!</P><P>&nbsp;</P><P>I have the board listed above and ended up loading in a sample code which placed my board into secure mode.

This was sent from "PGO" and it has worked for me so I hope that it works for you!</P></BODY></HTML> Tue, 17 May 2011 02:36:05 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Adapt9s12D-MC9s12dg128-Unsecuring/m-p/205794#M8355 jonathan_abbati 2011-05-17T02:36:05Z
