Instruction Execution Timing
10.6 STANDARD INSTRUCTION EXECUTION TIMES
Table 10-9 shows the number of clock cycles required for execution of the standard instruc-
tions, including completion of the operation and storing of the result. The number of operand
read and write cycles is shown in parentheses (r/w). In this table, <ea> denotes any effective
address and <M> denotes a memory operand. For all instructions in Table 10-9, the clock
cycles and r/w cycles for the effective address calculation (Table 10-5) must be added to the
values listed.

(d16,An), and (d16,PC)
Word divides have conditional exit points.
For entries in this column, add one cycle if the <ea> is (Ay)+, –(Ay) and Ay = An
Add one cycle to the effective address calculation time for all addressing modes except Rn, (An), (An)+, –(An),
