To power up: The PWR button brings the SHDN button high, turning everything
on. The processor keeps the SHDN pin high after after it boots up.
To power down: Monitor the PWR button, set the SHDN pin low when it is
pressed. Question. I need the diode to separate the "keep on" voltage from
the PWR button signal. I'm not sure I have this correct.
