5.7.2.2 CALCULATE EFFECTIVE ADDRESS. The calculate EA table indicates the num-
ber of clock periods needed for the processor to calculate a specified EA. The timing is
equivalent to fetch EA except there is no read cycle. The tail and cycle time are reduced by
the amount of time the read would occupy. 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.

NOTES:
1. Replacement fetches overlap the head of the operation by the amount specified in the tail.
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 head
5. Timing is calculated with the CPU32+ in 16-bit mode
