ADD: Add :- This instruction adds an immediate contents of a memory location specified in the a register ( source ) or instruction to the contents of another register (destination) or memory location. The outcome is in the destination operand. However, the source and destination both operands can't be memory operands. That means memory and memory addition is impossible. Also the contents of segment registers can't be added by using this instruction. All of the condition code flags are affected, depending on the result. The instance of this instruction is given along with the equivalent modes.
1. ADD AX, 0100H Immediate
2. ADD AX, BX Register
3. ADD AX, [SI] Register indirect
4. ADD AX, [5000H] Immediate
5. ADD [5000H] 0100H Immediate
6. ADD 0100H Destination AX (implicit)
