Function
BXOR B C ⊕ (<bit-No.> of <EAd>) → C
XORs the C flag with a specified bit in a general register or
memory, 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, 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 to the C flag.
BILD B ~ (<bit-No.> of <EAd>) → C
Copies the inverse of a specified bit in a general register or
memory 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.
BIST B ~ C → (<bit-No.> of <EAd>)
Copies the inverse of the C flag to a specified bit in a general
register or memory.
The bit number is specified by 3-bit immediate data.
