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'.
