Hello Freescale community. I have what I hope is a pretty simple question. I am using a MC68HC705C8ACPE and want to change to the MC68HC705C8AFNE version. Can I use the same HEX file to program the FNE version. The only difference between the two is the package. I am changing from a 40 pin dip to a 44 pin PLCC. I have built a prototype board to test the new chip but can not get it to work. It seems that the MCU is not working. Is this because the program needs to be changed in some way?
