Rotate right [f] through Carry
RRF
0 ≤ f ≤ FFh
d ∈ [0,1]
[Destination<n-1>] ← [f<n>]
[Destination<7>] ← C
C ← [f<7>]
C
[f] is rotated one bit to the
right through the Carry bit. If
d is 0, the result is stored in
the W register. If d is 1, the
result is stored back in [f].

Please make sure that all interrupt flags are cleared
before running SLEEP; "NOP" command must follow
HALT and SLEEP commands.
