5.7.2.1 FETCH EFFECTIVE ADDRESS. The fetch EA table indicates the number of clock
periods needed for the processor to calculate and fetch the specified EA. The total number
of clock cycles is outside the parentheses. The numbers inside parentheses (r/p/w) are
included in the total clock cycle number. All timing data assumes two-clock reads and writes.

word has been in the instruction pipeline for at least one cycle. This does not apply to
long offsets or displacements.

X = There is one bus cycle for byte and word operands and two bus cycles for long-word operands.
For long-word bus cycles, add two clocks to the tail and to the number of cycles.
NOTES:

1. The read of the EA and replacement fetches overlap the head of the operation by the amount
2. Size and scale of the index register do not affect execution time.
3. The PC may be substituted for the base address register An.
4. When adjusting the prefetch time for slower buses, extra clocks may be subtracted from the
5. Timing is calculated with the CPU32+ in 16-bit mode.
