MLIL: Unsigned Multiplication Byte or Word: This instruction multiplies an unsigned byte or word by the contents of the AL. The unsigned byte or word can be in any one of the general-purpose registers / memory locations. Most significant word of the result is stored in the resister DX, whereas the least significant word of the result is stored in the resister AX. All the flags are modified depending on the result. The example of the instructions is as shown. Immediate operand is not permitted in this instruction. If the most significant byte or word of the result is the '0' CF and OF both will be set.
