Data tranfer instructions are the instructions which transfers data in the microprocessor. They are also called copy instructions.
Following is the table showing the list of data transfer instructions:
|MOV||D, S||D = S||MOV AX, [SI]|
|PUSH||D||pushes D to the stack||PUSH DX|
|POP||D||pops the stack to D||POP AS|
|PUSHA||none||put all the registers into the stack||PUSHA|
|POPA||none||gets words from the stack to all registers||POPA|
|XCHG||D, S||exchanges contents of D snd S||XCHG , AX|
|IN||D, S||copies a byte or word from S to D||IN AX, DX|
|OUT||D, S||copies a byte or word from D to S||OUT 05, AL|
|XLAT||none||translates a byte in AL using a table in the memory||XLAT|
|LAHF||none||loads AH with the lower byte of the flag register||LAHF|
|SAHF||none||stores AH register to lower byte of the flag register||SAHF|
|PUSHF||none||copies the flag register at the top of the stack||PUSHF|
|POPF||none||copies a word at the top of the stack to the flag register||POPF|
Here D stands for destination and S stands for source.
D and S can either be register, data or memory address.
