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

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)
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

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.

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