Description:
Rotate Left f through Carry
[ label ] RLF f,d
0 ≤ f ≤ 127
d ∈ [0,1]
See description below
C
00 1101 dfff ffff
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'.
