MOV - 8086

Copy operand2 to operand1.
The MOV instruction cannot:
set the value of the CS and IP registers.
copy value of one segment register to another segment register (should copy to general register first).
copy immediate value to segment register (should copy to general register first).
Algorithm:
operand1 = operand2

Syntax

MOV REG, memory
MOV memory, REG
MOV REG, REG
MOV memory, immediate
MOV REG, immediate
MOV SREG, memory
MOV memory, SREG
MOV REG, SREG
MOV SREG, REG

Example

ORG 100h
 MOV AX, 0B800h ; set AX = B800h (VGA memory).
 MOV DS, AX ; copy value of AX to DS.
 MOV CL, 'A' ; CL = 41h (ASCII code).
 MOV CH, 01011111b ; CL = color attribute.
 MOV BX, 15Eh ; BX = position on screen.
 MOV [BX], CX ; w.[0B800h:015Eh] = CX.
