Skoro nie ma napisane to nóżka pozostanie w tym stanie. Jest nawet ostrzeżenie by nie sterować obciążeń rezystancyjnych w celu zmniejszenia poboru mocy.
Jedynie w nóżkach skonfigurowanych jako wejście zostaną odłączone bufory wejściowe (sygnał SLEEP).
Cytat: Port Pins
When entering a sleep mode, all port pins should be configured to use minimum power. The most important is then to ensure that no pins drive resistive loads. In sleep modes where both the I/O clock and the ADC clock are stopped, the input buffers of the device will be disabled. This ensures that no power is consumed by the input logic when not needed. In some cases, the input logic is needed for detecting wake-up conditions, and it will then be enabled. Refer to the section “Digital Input Enable and Sleep Modes” on page 74 for details on which pins are enabled. If the input buffer is enabled and the input signal is left floating or have an analog signal level close to Vcc/2, the input buffer will use excessive power.
