d
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’.
Rotate Left f through Carry

d
See description below
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’.

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.

(f) - (W)
Subtract W from f
[ label ] SUBWF f,d
0
d
Subtract (2’s complement method)
W register from register 'f'. If 'd' is 0,
the result is stored in the W regis-
ter. If 'd' is 1, the result is stored
back in register 'f'.
Subtract W from Literal
[ label ] SUBLW k

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.
Swap Nibbles in f

None
The upper and lower nibbles of
register 'f' are exchanged. If 'd' is
0, the result is placed in W regis-
ter. If 'd' is 1, the result is placed in
register 'f'.
