BSET

→ (<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

BCLR

→ (<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

BNOT

¬ (<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

¬ (<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

BIAND

∧ (<bit-No.> of <EAd>) → C

ANDs the carry flag with a specified bit in a general

carry flag.

∧ ¬ (<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

BIOR

∨ (<bit-No.> of <EAd>) → C

ORs the carry flag with a specified bit in a general

carry flag.

∨ ¬ (<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.
