This instruction can be used with a LOCK prefix to allow the instruction to be executed atomically. To simplify the
interface to the processor’s bus, the destination operand receives a write cycle without regard to the result of the
comparison. The destination operand is written back if the comparison fails; otherwise, the source operand is
written into the destination. (The processor never produces a locked read without also producing a locked write.)
