Table 2.7 Bit Manipulation Instructions (2)
Instruction Size* Function
BXOR B C ⊕ (<bit-No.> of <EAd>) → C
Logically exclusive-ORs the carry flag with a specified bit in a general
register or memory operand and stores the result in the carry flag.
BIXOR B C ⊕ ∼ (<bit-No.> of <EAd>) → C
Logically exclusive-ORs the carry flag with the inverse of a specified
bit in a general register or memory operand and stores the result in
the carry flag.
The bit number is specified by 3-bit immediate data.
BLD B (<bit-No.> of <EAd>) → C
Transfers a specified bit in a general register or memory operand to
the carry flag.
BILD B ∼ (<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 B C → (<bit-No.> of <EAd>)
Transfers the carry flag value to a specified bit in a general register
or memory operand.
BIST B ∼ C → (<bit-No.>. of <EAd>)
Transfers the inverse of the carry flag value to a specified bit in a
general register or memory operand.
The bit number is specified by 3-bit immediate data.
Note: * Size refers to the operand size.
