Table 2.7 Bit Manipulation Instructions (1)
Instruction Size * Function
BSET B 1
→ ( of )
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
→ ( of )
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
∼ ( of ) → ( of )
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
∼ ( of ) → 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
∧ ( of ) → C
Logically 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
∧ ( of ) → C
Logically 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
∨ ( of ) → C
Logically 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
∨ (∼ of ) → C
Logically 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.
B: Byte
