Return with Literal in W
[ label ]
0 ≤ k ≤ 255
k → (W);
TOS → PC
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.
Rotate Left f through Carry
[ label ]
0 ≤ f ≤ 31
d ∈ [0,1]
See description below
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’.
Rotate Right f through Carry
[ label ]
0 ≤ f ≤ 31
d ∈ [0,1]
See description below
The contents of register ‘f’ are
rotated one bit to the right through
the Carry flag. If ‘d’ is ‘0’, the result
is placed in the W register. If ‘d’ is
‘1’, the result is placed back in
register ‘f’.

Enter SLEEP Mode
[label ]
None
00h → WDT;
0 → WDT prescaler;
1 → TO;
0 → PD
Time-out Status bit (TO) is set. The
Power-down Status bit (PD) is
cleared.
RBWUF is unaffected.
The WDT and its prescaler are
cleared.
The processor is put into Sleep
mode with the oscillator stopped.
See Section 7.9 “Power-down
Mode (Sleep)” on Sleep for more
details.
Subtract W from f
[label ]
0 ≤ f ≤ 31
d ∈ [0,1]
(f) – (W) → (dest)
Subtract (2’s complement method)
the W register from register ‘f’. If ‘d’
is ‘0’, the result is stored in the W
register. If ‘d’ is ‘1’, the result is
stored back in register ‘f’.
Swap Nibbles in f
[ label ] SWAPF f,d
0 ≤ f ≤ 31
d ∈ [0,1]
(f<3:0>) → (dest<7:4>);
(f<7:4>) → (dest<3:0>)
The upper and lower nibbles of
register ‘f’ are exchanged. If ‘d’ is
‘0’, the result is placed in W
register. If ‘d’ is ‘1’, the result is
placed in register ‘f’.
