See description below
C
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'

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.

C, DC, Z
The W register is subtracted (2’s com-
plement method) from the eight bit literal
'k'. The result is placed in the W register.
