Table 2-7 Bit Manipulation Instructions
Instruction Size* Function
1 → (<bit-No.> of <EAd>)
BSET B
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 3 bits of a general
register.
0 → (<bit-No.> of <EAd>)
BCLR B
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 3 bits of a general
register.
¬ (<bit-No.> of <EAd>) → (<bit-No.> of <EAd>)
BNOT B
Inverts a specified bit in a general register or memory operand. The bit
number is specified by 3-bit immediate data or the lower 3 bits of a general
register.
¬ (<bit-No.> of <EAd>) → Z
BTST B
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 3 bits of a general register.
C ∧ (<bit-No.> of <EAd>) → C
BAND B
ANDs 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
BIAND B
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.
Note: * Size refers to the operand size.
B: Byte
