All the Datasheet say is :
"The External reset pin is default high by an internal 75Kohm and should be left floating if not used. To initiate a reset the pin needs to be pulled low. The module also initiates a reset if the VCC drops below the minimum 2.8V supply."
Am I missing a user guide/manual? This documentation seems a bit thin. I have the Datasheet for what it is, the NMEA Packet definition and NMEA sentence definition.
