16 Bit number divided by an 8 bit number
The given program displays the set of instructions for division of a 8 bit number from a 16 bit number.
div Unsigned divide
Syntax: div op8
div op16
op8: 8-bit register or memory
op16: 16-bit register or memory
Action: If operand is op8, unsigned AL = AX / op8 and AH = AX % op8
If operand is op16, unsigned AX = DX::AX / op16 and DX = DX::AX % op16
Flags Affected: OF=?, SF=?, ZF=?, AF=?, PF=?, CF=?
Notes: Performs both division and modulus operations in one instruction.
