RRF

Rotate Right f through Carry

Syntax:

[ label ] RRF f,d

Operands:

0 ≤ f ≤ 127

d ∈ [0,1]

Operation:

See description below

Status Affected: C

Description:

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

SUBWF

Subtract W from f

Syntax:

[ label ] SUBWF f,d

Operands:

0 ≤ f ≤ 127

d ∈ [0,1]

Operation:

(f) - (W) → (destination)

Status Affected: C, DC, Z

Description:

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’.

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.

SWAPF

Swap Nibbles in f

Syntax:

Operands:

Operation:

Status Affected:

Description:

[ label ] SWAPF f,d

0 ≤ f ≤ 127

d ∈ [0,1]

(f<3:0>) → (destination<7:4>),

(f<7:4>) → (destination<3:0>)

None

The upper and lower nibbles of

register ‘f’ are exchanged. If ‘d’ is

‘0’, the result is placed in the W

register. If ‘d’ is ‘1’, the result is

placed in register ‘f’.

XORLW

Syntax:

Operands:

Operation:

Status Affected:

Description:

Exclusive OR Literal with W

[label] XORLW k

0 ≤ k ≤ 255

(W) .XOR. k → (W)

Z

The contents of the W register

are XOR’ed with the eight-bit

literal ‘k’. The result is placed in

the W register.
