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’.

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’.
