We are in the process of porting Forth (SwiftX) to the MCF52235. The reference manual is incomplete with omissions, obvious errors and inconsistencies. I have been able to fill some of the gaps looking at the flood of code generated by CodeWarrior 6.3


1. The latest published reference manual ( MCF52235RM (06/2006, Rev 1 )) is a mess, specifically Appendix A. There are entire address ranges missing. And in the main body of the manual, there are conflicts, errors, and omissions. Tables 15-13 and 15-14 (Interrupt Sources) are full of errors. There are duplicate EPORT sources (and there is no EPF0 !!) in 15-14.

2. The chip status is Active and the RM is still preliminary! Is there a less-preliminary version?

3. I have made a comparison between the header files created by CodeWarrior 6.3 ( which was shipped with the M52235EVB ) and the register addresses from the manual and it seems the CodeWarrior people worked from a different manual than the one published on your web site. I cannot help to wonder what inside source the CodeWarrior people used. It surely was not this manual!
