RLF

Rotate Left f through Carry

Syntax:

Operands:

Operation:

[ label ] RLF f,d

0 ≤ f ≤ 127

d ∈ [0,1]

See description below

Status Affected:

Description:

C

The contents of register 'f' are rotated

one bit to the left through the Carry

Flag. If 'd' is 0, the result is placed in

the W register. If 'd' is 1, the result is

stored back in register 'f'.

C

Register f

RETURN

Syntax:

Operands:

Operation:

Status Affected:

Description:

Return from Subroutine

[ label ] RETURN

None

TOS → PC

None

Return from subroutine. The stack

is POPed and the top of the stack

(TOS) is loaded into the program

counter. This is a two-cycle

instruction.

RRF

Syntax:

Operands:

Operation:

Status Affected:

Description:

Rotate Right f through Carry

[ label ] RRF f,d

0 ≤ f ≤ 127

d ∈ [0,1]

See description below

C

The contents of register 'f' are

rotated one bit to the right through

the Carry Flag. If 'd' is 0, the result

is placed in the W register. If 'd' is

1, the result is placed back in

register 'f'.

C

Register f

SLEEP

Syntax:

Operands:

Operation:

Status Affected:

Description:

[ label ] SLEEP

None

00h → WDT,

0 → WDT prescaler,

1 → TO,

0 → PD

TO, PD

The power-down STATUS bit,

PD is cleared. Time-out STATUS

bit, TO is set. Watchdog Timer

and its prescaler are cleared.

The processor is put into SLEEP

mode with the oscillator stopped.

SUBLW

Subtract W from Literal

Syntax:

[ label ] SUBLW k

Operands:

0 ≤ k ≤ 255

Operation:

k - (W) → (W)

Status Affected: C, DC, Z

Description:

The W register is subtracted (2’s

complement method) from the

eight-bit literal 'k'. The result is

placed in the W register.

SUBWF

Syntax:

Operands:

Operation:

Status

Affected:

Description:

Subtract W from f

[ label ] SUBWF f,d

0 ≤ f ≤ 127

d ∈ [0,1]

(f) - (W) → (destination)

C, DC, Z

Subtract (2’s complement method)

W register from register 'f'. If 'd' is 0,

the result is stored in the W

register. If 'd' is 1, the result is

stored back in register 'f'.
