I'll take a bit of a stab in the dark here ...
By a/d converter, you mean analog to digital converter?

If so, is this the same unit found in the 68HC11?

(I would have thought the 68HC12 would have been some kind of co-processor to the 68HC11 ... guess not.)

I will get back to you as soon as I have done a bit of research into your problem, but in the meantime, do you have the manual for the chip?
I have the book for the 68HC11 ... only it's packed right now, but I'll see what I can do.

The documentation for the 68hc12 are linked there ...
If you can download those, you'll have all the opcodes and interrupts. You may need to get the doc for whatever microcode OS you are running ... I was using a modified buffalo OS at uni ...
