For calibration, basic version does not contain any calibration addresses, it depends on calibration tool to convery the addresses to the driver. Since Alpha and Beta firmware, all the calibration addresses are saved into the firmware. In order to fallback the BASIC or older version, code was added an extra branch to handle Alpha and Beta version.
