Set

AL to

the contents of DS:[rBX +

unsigned AL].

XOR

the

contents

of

AL

with

an

XOR AL,imm8

34

ib

immediate 8-bit operand and store the

result in AL.

XOR

the

contents

of

AX

with

an

XOR AX,imm16

35

iw

immediate

16-bit

operand

and

store

the result in AX.

XOR

the

contents

of

EAX

with

an

XOR EAX,imm32

35

id

immediate

32-bit

operand

and

store

the result in EAX.

XOR the contents of RAX with a sign-

XOR RAX,imm32

35

id

extended immediate 32-bit operand and

store the result in AX.

XOR the contents of an 8-bit

destination

register

or

memory

XOR reg/mem8,imm8

80

/6 ib

operand with an 8-bit immediate value

and

store

the

result

in

the

destination.

XOR the contents of a 16-bit

destination

register

or

memory

XOR reg/mem16,imm16

81

/6 iw

operand with a 16-bit immediate value

and

store

the

result

in

the

destination.

XOR the contents of a 32-bit

destination

register

or

memory

XOR reg/mem32,imm32

81

/6 id

operand with a 32-bit immediate value

and

store

the

result

in

the

destination.

XOR the contents of a 64-bit

destination

register

or

memory

XOR reg/mem64,imm32

81

/6 id

operand

with

a sign-extended 32-bit

immediate value and store the result

in the destination.

XOR the contents of a 16-bit

destination

register

or

memory

XOR reg/mem16,imm8

83

/6 ib

operand

with

a sign-extended 8-bit

immediate value and store the result

in the destination.

XOR the contents of a 32-bit

destination

register

or

memory

XOR reg/mem32,imm8

83

/6 ib

operand

with

a sign-extended 8-bit

immediate value and store the result

in the destination.

XOR the contents of a 64-bit

destination

register

or

memory

XOR reg/mem64,imm8

83

/6 ib

operand

with

a sign-extended 8-bit

immediate value and store the result

in the destination.

XOR the contents of an 8-bit

destination

register

or

memory

XOR reg/mem8,reg8

30

/r

operand with the contents of an 8-bit

register and store the result in the

destination.

XOR the contents of a 16-bit

destination

register

or

memory

XOR reg/mem16,reg16

31

/r

operand with the contents of a 16-bit

register and store the result in the

destination.

XOR the contents of a 32-bit

destination

register

or

memory

XOR reg/mem32,reg32

31

/r

operand with the contents of a 32-bit

register and store the result in the
