Function
C ⊕ (<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.
∼
C ⊕ [
(<bit-No.> of <EAd>)] → C
XORs 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
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.
C → (<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 register or memory operand.
The bit number is specified by 3-bit immediate data.
