System Reset
Pin 3 of the multifunction connector allows connection of an external push-button to manually reset
the system. The push-button should be normally open, and connect to ground when pushed.
Battery
Pin 9 of the multifunction connector is the connection for an external backup battery (in the range
2.40 V to 4.15 V; typically 3.0 or 3.6 V). This battery is used by the cpuModule when system power
is removed, to preserve the date and time in the Real Time Clock
