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