Description:
Rotate Left f (no carry)
[ label ] RLNCF f,d
0  f  255
d  [0,1]
f<n>  d<n+1>;
f<7>  d<0>
None
0010 001d ffff ffff
The contents of register 'f' are rotated
one bit to the left. If 'd' is 0, the result is
placed in WREG. If 'd' is 1, the result is
stored back in register 'f'.

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
WREG. If 'd' is 1, the result is placed
back in register 'f'.
