7.11 MISCELLANEOUS INSTRUCTION EXECUTION TIMES
Tables 7-13 and 7-14 list the timing data for miscellaneous instructions. The total number
of clock periods, the number of read cycles, and the number of write cycles are shown in
the previously described format. The number of clock periods, the number of read cycles,
and the number of write cycles, respectively, must be added to those of the effective
address calculation where indicated by a plus sign (+).
