This section summarizes instruction timings for the M68040. The timings are divided into
two groups: integer unit and floating-point unit instruction timings. Each group is further
subdivided to separate more complex instruction timings. Each of these subdivided groups
is in alphabetical order with no reference to mode. Table 10-1 alphabetically lists
instruction timings and their location in this section.
