Function

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 3 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 3 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 3 bits of a general

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 3 bits of a general register.

BAND

∧(<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

∧[¬ (<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.

Note: * Size refers to the operand size.

B: Byte
