Pin 2: VBATT Voltage
This pin provides the battery backup power to run the RTC. This voltage
must
be supplied
during normal mode of operation even when battery backup is not required.
Pin 3: Host port serial data output (TXD)
The host port consists of a full-duplex asynchronous serial data interface. Both binary and
NMEA initialisation and configuration data messages are transmitted and received across
this port. Port Idle is a CMOS logic high level.
Pin 4: Host port serial data input 1 (RXD)
This is the data input to the module.
Pin 5: BOOT
Pull this pin high during start-up to reprogram the Flash memory.
