Checksum type 1 consists of two hexadecimal digits, which represent the result of a
XOR from all characters comprised between `\$' and `*' (`\$' e `*' not included). It is
useful for NMEA datagrams.
One example of serial datagram is presented below:
''Day:%d;Month:%m;Year:%Y;Hour:%H;Minute:%M;Second:%S;;%3''
The table below presents all configurable parameters for the time synchronization
