Hard Reset
The Digi Connect Wi-ME 9210 module supports a hardware reset via pin 8 of the 14-pin header.
The unit is forced into a hard reset when pulling the pin to ground, or less than 0.8v, for one
microsecond. When plugged into a development board, this pin is wired to the push button at SW4.
As a result, this switch acts as a hard reset button.
