If you want to get S12X SCI interrupt info, go to my site at:
http://mamoru.tbreesama.googlepages.com/I have a page explaining how to do interrupts with the S12X, using the SCI
as an example. Furthermore, the code source I have posted includes a
working, tested, and verified SCI interrupt handler. (In assembly, of
course.) Of course, this is with the S12XD, but I assume it should be
similar/identical for the S12XS.
Have Fun!
