DESCRIPTION

been pressed. The signal remains high for the
duration of the button press.
If the FlipTop cover is not fully open the
buttons are disabled and the unit will not
report any button presses, and will release
any button that is already pressed. The status
of the cover is given by the < FlipTopOpen >
output.
If two buttons are combined to form one larger
button, the same signal should be attached to
both button presses.
High/1 = Button pressed; Low/0 = Button

as the input is high.
If two buttons are combined, then only the
LED for the top button in the vertical pair will
be visible.
