- I have a 68020 reference manual on my hand, but unfortunately, I don't
- have '030 or '040 reference manual. So here goes my questions:
-
- 1.) Am I correct in my understanding that the newer chips throw the
- CALLM/RTM opcodes away? If so, then what happens to the
- corresponding machine opcodes? Are they turned into illegal
- instructions or what?
-
- 2.) I'd like to know the new opcodes (both machine and mnemonic) for
- both '030 and '040...and be sure to mark them as such (e.g. this
- XXX.W is '030 addition; and also mark it as privileged if so)
- I only need a one line description per opcode in question (e.g.
- BTST --- Bit Test <blab, blab>; clearly the total lines devoted
- to each opcode should be at most three lines or so)
- The reason: to add new decoding logic to my disassembler, which I
- then use it as a springboard for my next project...
- (Remark: My disassembler works fine for 680x0 with x=0, 1, and 2;
- and I have the AmigaDOS reference book, 3rd ref., so no
- problem decoding the latest object/load formaats ;-)
-
- Of course if you happens to have a pointer to a good disassembler that
- can handle '030 or even '040 (it must have the source code), you can quote
- the source in lieu of Question #2.
- Thanks for the input! ----- and oh by the way, since I don't often read
- the UseNet stuff (being busy), I would greatly appreciate your e-mailing
- directly to me these information!
