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:

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'
.

Description:
The power-down status bit, PD is
cleared. Timeout status bit, TO is
set. Watchdog Timer and its
prescaler are cleared.
The processor is put into SLEEP
mode with the oscillator stopped.
