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.

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’.

TO, PD
00 0000 0110 0011
The power-down status bit, PD is
cleared. Time-out status bit, TO is
set. Watchdog Timer and its
prescaler are cleared.
The processor is put into SLEEP
mode with the oscillator stopped.
See Section 10.8 for more details.
