INSTRUCTION SET DESCRIPTIONS

Table C-4. Instruction Set (Continued)

Name	Description	Operation	Flags
			Affected
LOOPNE	Loop While Not Equal:	(CX) ← (CX) – 1	AF –
LOOPNZ	Loop While Not Zero:	if	CF –
	LOOPNE disp8	(ZF) = 0 and (CX) ≠ 0	DF –
		then	IF –
	LOOPNZ disp8
		(IP) ← (IP) + disp8 (sign-ext to 16 bits)	OF –
	Decrements CX by 1 and transfers
			PF –
	control to the target location if CX is
			SF –
	not 0 and if ZF is clear; otherwise the
			TF –
	next sequential instruction is executed.
			ZF –
	Instruction Operands:
	LOOPNE short-label
	LOOPNZ short-label
MOV	Move (Byte or Word):	(dest)←(src)	AF –
	MOV dest, src		CF –
			DF –
	Transfers a byte or a word from the
			IF –
	source operand to the destination
			OF –
	operand.
			PF –
	Instruction Operands:
			SF –
	MOV mem, accum		TF –
	MOV accum, mem		ZF –
	MOV reg, reg
	MOV reg, mem
	MOV mem, reg
	MOV reg, immed
	MOV mem, immed
	MOV seg-reg, reg16
	MOV seg-reg, mem16
	MOV reg16, seg-reg
	MOV mem16, seg-reg

NOTE: The three symbols used in the Flags Affected column are defined as follows:

–the contents of the flag remain unchanged after the instruction is executed ¸? the contents of the flag is undefined after the instruction is executed

the flag is updated after the instruction is executed
