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'.

Example: RLF REG1,0
Before Instruction
REG1 = 1110 0110
C=0
After Instruction
REG1 = 1110 0110
W=1100 1100

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.
