To differentiate a toggle type from a momentary type, check the On and Off
switch position. In a toggle type switch, a pressed switch indicates On
position while a normal switch position indicates Off. In a momentary type,
the switch position does not change for both modes.
To support a toggle type switch, close pins 2-3 of JP14. Close all pins (1-4)
to support a momentary type switch.
