Description:
Rotate Right f through Carry
[ label ]
0
d
See description below
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’.
Subtract W from Literal
[ label ] SUBLW k
0
k - (W)
The W register is subtracted (2’s
complement method) from the
eight-bit literal ‘k’. The result is
placed in the W register.

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.

Subtract W from f
[ label ] SUBWF f,d
0
d
(f) - (W)
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’.
Swap Nibbles in f

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’.
(W) .XOR. k

Exclusive OR Literal with W
[label]
0
The contents of the W register
are XOR’ed with the eight-bit
literal ‘k’. The result is placed in
the W register.
