Time-out status bit (TO) is set. The
power down status bit (PD) is cleared.
GPWUF is unaffected.
The WDT and its prescaler are
cleared.
The processor is put into SLEEP mode
with the oscillator stopped. See sec-
tion on SLEEP for more details.

d
(f) – (W)
Subtract (2’s complement method) the
W register from register 'f'. If 'd' is 0 the
result is stored in the W register. If 'd' is
1 the result is stored back in register 'f'.
