RETURN
[Top Stack] => PC
Pop Stack
None
The program counter is loaded
from the top stack, then pop
stack.

Rotate right [f] through Carry
RRF f, d
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].

Flag Affected
Description
Cycle
Please make sure that all interrupt flags are cleared
before running SLEEP; "NOP" command must follow
HALT and SLEEP commands.
Oscillator stop
SLEEP
CPU oscillator is stopped
PD
CPU oscillator is stopped. CPU
can be waked up by external
interrupt sources.

Rotate left [f] through Carry
RLF f, d
0 ≤ f ≤ FFh
d ∈ [0,1]
[Destination<n+1>] ← [f<n>]
[Destination<0>] ← C
C ← [f<7>]
C, Z
[f] is rotated one bit to the left
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].
