Return from Interrupt
[ label ]
None
TOS → PC,

None
Return with Literal in W
[ label ]
0 ≤ k ≤ 255
k → (W);
TOS → PC
None
The W register is loaded with the
eight-bit literal ‘k’. The program
counter is loaded from the top of
the stack (the return address).
This is a two-cycle instruction.
Return from Subroutine
[ label ]
None
TOS → PC
None
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.

Rotate Right f through Carry
[ label ]
0 ≤ f ≤ 127
d ∈ [0,1]
See description below
C
The contents of register ‘f’ are
rotated one bit to the right through
the Carry Flag. If ‘d’ = ‘0’, the
result is placed in the W register.
If ‘d’ = ‘1’, the result is placed back
in register ‘f’.
Rotate Left f through Carry
[ label ]
0 ≤ f ≤ 127
d ∈ [0,1]
See description below
C
The contents of register ‘f’ are
rotated one bit to the left through
the Carry Flag. If ‘d’ = ‘0’, the
result is placed in the W register.
If ‘d’ = ‘1’, the result is stored
back in register ‘f’.
[ label ]
None
00h → WDT,
0 → WDT prescaler,
1 → TO,
0 → PD
TO, PD
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.
