PREFACE
The complete documentation package for the MC68040, MC68040V, MC68LC040,
MC68EC040, and MC68EC040V (collectively called M68040) consists of the
M68040UM/AD, M68040 User’s Manual, and the M68000PM/AD, M68000 Family
Programmer’s Reference Manual. The M68040 User’s Manual describes the capabilities,
operation, and programming of the M68040 32-bit third-generation microprocessors. The
M68000 Family Programmer’s Reference Manual contains the complete instruction set for
the M68000 family.
The introduction of this manual includes general information concerning the MC68040 and
summarizes the differences between the M68040 member devices. Additionally, three
appendices provide detailed information on how these M68040 dirivatives operate
differently from the MC68040. For detailed information on one of these M68040
dirivatives, use the following table to determine which appendices to read in conjunction
with the rest of this manual.
