Table 2.7 Bit Manipulation Instructions
Instruction Size* Function
BSET B 1 → (<bit-No.> of <EAd>)
Sets a specified bit in a general register or memory operand to 1. The bit
number is specified by 3-bit immediate data or the lower three bits of a
general register.
BCLR B 0 → (<bit-No.> of <EAd>)
Clears a specified bit in a general register or memory operand to 0. The
bit number is specified by 3-bit immediate data or the lower three bits of
a general register.
BNOT B ∼ (<bit-No.> of <EAd>) → (<bit-No.> of <EAd>)
Inverts a specified bit in a general register or memory operand. The bit
number is specified by 3-bit immediate data or the lower three bits of a
general register.
BTST B ∼ (<bit-No.> of <EAd>) → Z
Tests a specified bit in a general register or memory operand and sets or
clears the Z flag accordingly. The bit number is specified by 3-bit
immediate data or the lower three bits of a general register.
BAND B C ∧ (<bit-No.> of <EAd>) → C
ANDs the carry flag with a specified bit in a general register or memory
operand and stores the result in the carry flag.
BIAND B C ∧ ∼ (<bit-No.> of <EAd>) → C
ANDs 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.
BOR B C ∨ (<bit-No.> of <EAd>) → C
ORs the carry flag with a specified bit in a general register or memory
operand and stores the result in the carry flag.
BIOR B C ∨ ∼ (<bit-No.> of <EAd>) → C
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.
Note: * Size refers to the operand size.
