1. When PWR is high , MSu001 audio output signal will stay at approx. 2.4V even there is no audio output .
2. When PWR is low , MSu001 audio output signal will stay at GND level when there is no audio output .
3. For eliminating the "pop" noise purpose , PWR should be at high level when a sound section is played
over , and also at high level in between two sound sections .
4. For energy saving purpose , PWR should not always stay at high level , since there will be a hundred-mA
current consumption when PWR is high . So it should go to low level when its not needed .
