I need an assembly language reference for the MPC8280.

I just spent a half hour on the website looking.  Doesn't seem like it should be so hard to find.

Thanks, Pavel.  The second option (Appendix B of the MPC823UM.pdf) was just what I was looking for (not so much the first).

Use Appendix A of the MPCFPE32B.pdf file or Appendix B of the MPC823UM.pdf file.

These files can be loaded using the following links:

Have a great day,

Ok, I found the G2 Core Ref Manual (G2CORERM.pdf).  It gives me the name and syntax.  Doesn't help if I don't know what it's doing.  I'm picturing a document with a page for each instruction, or a least a text description of what it does.  F'rinstance:

Mnemonic: addis    Name: Add Immediate Shifted   Syntax: rD,rA,SIMM (from G2CORERM)

OK (I infer), it adds the immediate value (SIMM) to rA and the result goes in rD.  What gets shifted?  By how much?

Even if I can't find the doc I expect, it would be a great help if someone can just explain this one instruction.

But c'mon, that document has to exist, right?    Thanks.
