Data transmission
Only «read/write» register instructions are recognized.
Only one register can ever be read/written at a time.
The device will not respond to any unknown query.
The «automatic transmission rate» is set by default.
The module has a voltage monitoring system. In case of
voltage loss, registers are stored in EEPROM.
