16 Bit Multiplication

The given program displays the set of instructions for a 16 bit subtraction of two numbers.

mul - Unsigned multiply
Syntax: mul op8
mul op16
op8: 8-bit register or memory
op16: 16-bit register or memory
Action: If operand is op8, unsigned AX = AL * op8
If operand is op16, unsigned DX::AX = AX * op16
Flags Affected: OF, SF=?, ZF=?, AF=?, PF=?, CF
