Beschreibung
Software waits till button gets removed.
This may result in very strange behaviour when battery is empty.
Maybe N-MOSFET is usefull anyways. Is wakeup on falling edge posible? No.
When battery voltage is at <=2,1V there is already a small feeddback to
the enable-line which causes pseudo-key-press and a power off via sofftware.
More critical: device is switched on when battery is low. Is there also a permanent discharge then?
Battery only lasts a couple of weeks.
(2800mAh / 20mA) / 24h = 5,833333333 days
Remove the battery and check for causing wire (voltage source) on RTC-Eval.

Is there really a voltage feed back when battery is removed? That would be not intended.
