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’.

Description:
Time-out Status bit (TO) is set. The
power-down Status bit (PD) is
cleared. The WDT and its
prescaler are cleared.
The processor is put into Sleep
mode with the oscillator stopped.
