Microchip Technology 

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:

Enter Sleep mode

[ 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 pres-

caler are cleared.

The processor is put into Sleep mode

with the oscillator stopped.

SUBLW

Syntax:

Operands:

Operation:

Status Affected:

Description:

Subtract W from literal

[ label ] SUBLW k

0 ≤ k ≤ 255

k - (W) → (W)

C, DC, Z

The W register is subtracted (2’s com-

plement method) from the eight-bit

literal ‘k’. The result is placed in the W

register.

C=0

C=1

DC = 0

DC = 1

W>k

W≤k

W<3:0> > k<3:0>

W<3:0> ≤ k<3:0>

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.

C=0

C=1

DC = 0

DC = 1

W>f

W≤f

W<3:0> > f<3:0>

W<3:0> ≤ f<3:0>

SUBWFB

Syntax:

Operands:

Operation:

Status Affected:

Description:

Subtract W from f with Borrow

SUBWFB f {,d}

0 ≤ f ≤ 127

d ∈ [0,1]

(f) – (W) – (B) → dest

C, DC, Z

Subtract W and the BORROW flag

(CARRY) from register ‘f’ (2’s comple-

ment method). If ‘d’ is ‘0’, the result is

stored in W. If ‘d’ is ‘1’, the result is

stored back in register ‘f’.
