= There is one bus cycle for byte and word operands and two bus cycles for long

operands. For long bus cycles, add two clocks to the tail and to the number of

cycles.

<= Maximum time (certain data or mode combinations may execute faster).

= The execution time is identical for signed or unsigned operands.

*These instructions have an additional save operation that other instructions do not have. To

calculate total instruction time, calculate save,

〈ea〉, and operation execution times, then

combine in the order shown, using equations in 5.7.1.6 Instruction Execution Time

Calculations. A save operation is not run for long-word divide and multiply instructions

when
