7.5 SINGLE OPERAND INSTRUCTION EXECUTION TIMES
Table 7-7 lists the timing data for the single operand 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 (+).
