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’.

TO is set. Watchdog Timer and
its prescaler are cleared.
The processor is put into Sleep
mode with the oscillator
stopped. See
