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.
Power Switch
Pin 4 of the multifunction connector allows connection of an external push-button switch to act as
an ATX power switch, or standby switch. 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 and preserve SRAM contents if the
SSD jumpers are configured for battery backup.
