Hi cheehowhng,
First of all - sorry for the delayed answered.
Unfortunately, this community is more about the tools related with Matlab/Simulink and the ecosystem around the software tools for the processors supported by our toolboxes, therefore we are not entitled to support parts we are not experts on due to high probability of being wrong.
My advice to you is to seek help in Microcontroller community that may put you in contact with experts on your matter: ColdFire/68K Microcontrollers and Processors
Thanks for your understanding!
Daniel
