The format for this instruction is: POP destination The POP instruction loads the word from the stack pointed by SP and then increments the SP by 2. MOV DL, +6 Load data from PA=DS(Shifted left)+BX+6 to DL Copy data from AX to physical address(PA) MOV, 6Ah Sets memory address 02712:0069 to 6Ah MOV SI, 25 Set SI to 0019 (decimal value of 25) DB is used for storing byte and DW is used for storing a word (2 bytes).
CX PROGRAMMER INSTRUCTION LIST CODE
In the code given below, a and b are the variables. Example Assembly CodeĬonsider an example to understand the behavior of MOV instruction. The MOV instruction does not affect any value in the flag register. Therefore, both source and destination operands cannot be memory address. It is not possible to transfer data directly from one memory location to another. The 8086 MOV instruction supports the following operands: Source Destination Example Reg Reg MOV AX, BL Memory Address Reg MOV CX, Reg Memory Address MOV, AH Immediate Reg MOV AL, 21C Immediate Memory Address MOV, 37B2 Segment Register Reg MOV AX, DS Reg Segment Register MOV CS, CX The destination operand can be any register or a memory location whereas the source operand can be a register, memory address, or a constant/immediate. The syntax of this instruction is: MOV Destination, Source Both operands should be of same type either byte or a word. The MOV instruction copies a byte or a word from source to destination.
