PIC16C62X
RLF Rotate Left f through Carry
Syntax: [ label ] RLF f,d
Operands: 0 ≤ f ≤ 127
d ∈ [0,1]
Operation: See description below
Status Affected: C
Encoding:
00 1101 dfff ffff
Description: 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'.

Example
RLF REG1,0
Before Instruction
REG1 = 1110 0110
C=0
After Instruction
REG1 = 1110 0110
W = 1100 1100
C=1

RRF Rotate Right f through Carry
Syntax: [ label ] RRF f,d
Operands: 0 ≤ f ≤ 127
d ∈ [0,1]
Operation: See description below
Status Affected: C
Encoding:
00 1100 dfff ffff
Description: 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'.

SLEEP
Syntax: [ label
]
SLEEP
Operands: None
Operation: 00h → WDT,
0 → WDT prescaler,
1 → TO,
0 → PD
Status Affected: TO, PD
Encoding:
00 0000 0110 0011
Description: The power-down STATUS bit,
PD
is cleared. Time-out
STATUS bit, TO
is set. Watch-
dog Timer and its prescaler are
cleared.
The processor is put into SLEEP
mode with the oscillator
stopped. See Section 9.8 for
more details.
