The host can send this message in order to save part of the BBR memory in a file in flash
file system. The feature is designed in order to emulate the presence of the backup battery
even if it is not present; the host can issue the save on shutdown command before
switching off the device supply. It is recommended to issue a GNSS stop command before,
in order to keep the BBR memory content consistent.
