Rotate Left f through Carry
[ label ] RLF
0
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’.
Return from Subroutine
[ label ]
None
TOS
None
Return from subroutine. The stack
is POPed and the top of the stack
(TOS) is loaded into the program
counter. This is a two-cycle
instruction.
Rotate Right f through Carry
[ label ]
0
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’.

d
(f) - (W)
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'.
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.

prescaler are cleared.
The processor is put into SLEEP
mode with the oscillator stopped.
