*

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

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

∧ (<bit-No.> of <EAd>) → 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

∨ (<bit-No.> of <EAd>) → 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

∨ (∼ <bit-No.> of <EAd>) → 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
