APPENDIX D
MC68060 INSTRUCTIONS
This appendix provides a quick reference to instructions of the MC68060 that differ in
description to the instruction description found in the
M68000 Family Programmer’s Refer-
ence Manual
(M68000PM/AD).
To provide a quick summary of which instructions require software assistance from the
M68060 software package (M68060SP), and to indicate differences of the MC68060 relative
to earlier members of the M68000 family, Table D-1 is provided. Table A-2 lists the M68000
family instructions by mnemonics followed by the descriptive name. Table D-3 provides all
assigned vector table entries up to, and including the MC68060. This may be useful for writ-
ing handlers that apply to multiple members of the M68000 family of processors.
Since some of the MC68060 instructions require software-assist from the MC68060SP, it is
assumed that the MC68060SP has already been installed properly in the system. Given this
assumption, most of the description found in the
M68000 FamilyProgrammer’s Reference
Manual
applies to the MC68060. In general, instruction descriptions that apply to the
M68000 family, MC68040 or M68040FPSP apply also to the MC68060 or MC68060SP,
unless otherwise provided in this appendix.
