Instruction Size*
Function
BXOR
B
C ⊕ (<bit-No.> of <EAd>) → C
XORs the C flag with a specified bit in a general register or memory
operand, and stores the result in the C flag.
BIXOR
B
C ⊕ [~(<bit-No.> of <EAd>)] → C
XORs the C flag with the inverse of a specified bit in a general register
or memory operand, and stores the result in the C flag.
The bit number is specified by 3-bit immediate data.
BLD
B
(<bit-No.> of <EAd>) → C
Copies a specified bit in a general register or memory operand to the C
flag.
BILD
B
~ (<bit-No.> of <EAd>) → C
Copies the inverse of a specified bit in a general register or memory
operand to the C flag.
The bit number is specified by 3-bit immediate data.
BST
B
C → (<bit-No.> of <EAd>)
Copies the C flag to a specified bit in a general register or memory
operand.
BIST
B
~ C → (<bit-No.> of <EAd>)
Copies the inverse of the C flag to a specified bit in a general register
or memory operand.
The bit number is specified by 3-bit immediate data.
Note: * Size: Operand size
B: Byte
Certain precautions are required in bit manipulation. See 2.9.2, Notes on Bit Manipulation, for
details.
