RLF
Rotate Left f through Carry
Syntax:
[ label ] RLF f, d
Operands:
0 ≤ f ≤ 31
d ∈ [0,1]
Operation:
See description below
Status Affected: C
Encoding:
0011 01df ffff
Description:
The contents of register ‘f’ are
rotated one bit to the left through
the Carry Flag (STATUS<0>). If ‘d’
is ‘0’, the result is placed in the W
register. If ‘d’ is ‘1’, the result is
stored back in register ‘f’.

RRF
Rotate Right f through Carry
Syntax:
[ label ] RRF f, d
Operands:
0 ≤ f ≤ 31
d ∈ [0,1]
Operation:
See description below
Status Affected: C
Encoding:
0011 00df ffff
Description:
The contents of register ‘f’ are
rotated one bit to the right through
the Carry Flag (STATUS<0>). If ‘d’
is ‘0’, the result is placed in the W
register. If ‘d’ is ‘1’, the result is
placed back in register ‘f’.

Sleep
Go into Standby Mode
Syntax:
[ label ] Sleep
Operands:
None
Operation:
00h → WDT;
0 → WDT prescaler; if assigned
1 → TO;
0 → PD
Status Affected: TO, PD
Encoding:
Description:
0000 0000 0011
Time-out Status bit (TO) is set. The
power-down Status bit (PD) is
cleared. The WDT and its
prescaler are cleared.
The processor is put into Sleep
mode with the oscillator stopped.
See section on Sleep for more
details.
