Bit Manipulation Instructions

Instruction

Size

Function

BSET

→ (<bit-No.> of <EAd>)

Sets a specified bit in the contents of a general register or a memory

location to 1. The bit number is specified by 3-bit immediate data or the

lower three bits of a general register.

BSET/cc

if cc, 1

→ (<bit-No.> of <EAd>)

If the specified condition is satisfied, this instruction sets a specified bit in

a memory location to 1. The bit number can be specified by 3-bit

immediate data, or by the lower three bits of a general register. The Z flag

status can be specified as a condition.

BCLR

→ (<bit-No.> of <EAd>)

Clears a specified bit in the contents of a general register or a memory

location to 0. The bit number is specified by 3-bit immediate data or the

lower three bits of a general register.

BCLR/cc

if cc, 0

→ (<bit-No.> of <EAd>)

If the specified condition is satisfied, this instruction clears a specified bit

in a memory location to 0. The bit number can be specified by 3-bit

immediate data, or by the lower three bits of a general register. The Z flag

status can be specified as a condition.

BNOT

∼ (<bit-No.> of <EAd>) → (<bit-No.> of <EAd>)

Inverts a specified bit in the contents of a general register or a memory

location. 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 the contents of a general register or a memory

location 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

BAND

∧ (<bit-No.> of <EAd>) → C

ANDs the carry flag with a specified bit in the contents of a general

bit number is specified by 3-bit immediate data.

BIAND

∧ [∼ (<bit-No.> of <EAd>)] → C

ANDs the carry flag with the inverse of a specified bit in the contents of a

general register or a memory location and stores the result in the carry

flag. The bit number is specified by 3-bit immediate data.

BOR

∨ (<bit-No.> of <EAd>) → C

ORs the carry flag with a specified bit in the contents of a general register

or a memory location and stores the result in the carry flag. The bit

number is specified by 3-bit immediate data.
