The Power-down mode is entered by executing a
SLEEP instruction.
If enabled, the Watchdog Timer will be cleared but
keeps running, the PD bit in the Status register is
cleared, the TO bit is set, and the oscillator driver is
turned off. The I/O ports maintain the status they had,
before SLEEP was executed (driving high, low or high-
impedance).

For lowest current consumption in this mode, all I/O
pins should be either at V
circuitry drawing current from the I/O pin and the
comparators, and V
that are high-impedance inputs should be pulled high
or low externally to avoid switching currents caused by
floating inputs. The T0CKI input should also be at V
or
contribution from on chip pull-ups on PORTB should be
considered.
