Note:
Q1: How is the low-battery event raised or canceled?
A1: The minimum value on LOW_DELAY parameter is 1 second. If the voltage remains lower
than the LOW_THRESHOLD in the duration of LOW_DELAY, the low-battery event will be
raised and immediately send a power button press signal to OS.
During the duration of LOW_DELAY, if the battery voltage is back to be higher than
LOW_THRESHOLD, the LOW_DELAY will be reset to predetermined value and stop count
down.
Therefore, the LOW_DELAY parameter acts as a filter to prevent incorrect low-battery-event
from happening.
