Hi:
Why don't
you send us your block diagram, and
your initial ideas for the system, and we'll be able to provide you with some feedback?
Please note that the 68HC11 is no longer manufactured and not recommended for new designs. You should move to the HC(S)08 family of microcontrollers.
Regards,
Alex
