9.6 SHIFT/ROTATE INSTRUCTION EXECUTION TIMES
Tables 9-12 and 9-13 list the timing data for the shift and rotate 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 (+).
