Function

BXOR

BIXOR

⊕ (<bit-No.> of <EAd>) → C

XORs the carry flag with a specified bit in a general register or memory

operand and stores the result in the carry flag.

⊕ ¬ (<bit-No.> of <EAd>) → C

XORs the carry flag with the inverse of a specified bit in a general

The bit number is specified by 3-bit immediate data.

BLD

BILD

(<bit-No.> of <EAd>)

→ C

Transfers a specified bit in a general register or memory operand to the

carry flag.

¬ (<bit-No.> of <EAd>)

→ C

Transfers the inverse of a specified bit in a general register or memory

operand to the carry flag.

The bit number is specified by 3-bit immediate data.

BST

BIST

→ (<bit-No.> of <EAd>)

Transfers the carry flag value to a specified bit in a general register or

memory operand.

¬ C

→ (<bit-No.> of <EAd>)

Transfers the inverse of the carry flag value to a specified bit in a general

The bit number is specified by 3-bit immediate data.

Note:

Refers to the operand size.

B: Byte
