Function
C ∨ (<bit-No.> of <EAd>) → C
BOR
B
ORs the carry flag with a specified bit in a general register or memory
operand and stores the result in the carry flag.
C ∨ [¬ (<bit-No.> of <EAd>)] → C
BIOR
B
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.
C ⊕ (<bit-No.> of <EAd>) → C
BXOR
B
Exclusive-ORs the carry flag with a specified bit in a general register or
memory operand and stores the result in the carry flag.
C ⊕ [¬ (<bit-No.> of <EAd>)] → C
BIXOR
B
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.
(<bit-No.> of <EAd>) → C
BLD
B
Transfers a specified bit in a general register or memory operand to the
carry flag.
¬ (<bit-No.> of <EAd>) → C
BILD
B
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.
C → (<bit-No.> of <EAd>)
BST
B
Transfers the carry flag value to a specified bit in a general register or
memory operand.
C → ¬ (<bit-No.> of <EAd>)
BIST
B
Transfers the inverse of the carry flag value to a specified bit in a general
register or memory operand.
