Intel 210200-002 manual MOV Move Byte or Word MOV, 11000111 0 Imod 0 reg r/ml

MOV MOVE (BYTE OR WORD) MOV

Encoding:

Memory Operand to Accumulator:

11 01 0000 w 1 addr-Iow 1 addr-high

if w = 0 then SRC = addr, DEST = AL else SRC = addr+ 1:addr, DEST = AX

Accumulator to Memory Operand:

1101 0001 w 1 addr-Iow 1 addr-high

if w = 0 then SRC = AL, DEST = addr else SRC = AX, DEST = addr+ 1:addr

Memory or Register Operand to Segment Register:

11000111 0 Imod 0 reg r/ml

if reg *01 then SRC = EA, DEST = REG else undefined operation

Segment Register to Memory or Register Operand:

11 00011 00 Imod 0 reg r I ml

SRC = REG,DEST = EA
