XMC_VADC_GLOBAL_StartupCalibration () does not confirm that CALS becomes 1.

The function XMC_VADC_GLOBAL_StartupCalibration () in the program below does not confirm that CALS becomes 1.
If it is not confirmed that CALS becomes 1 when the XMC is broken down, ADC may run without being calibrated.
Could you apply the correction to check that CALS becomes 1 to XMC_VADC_GLOBAL_StartupCalibration ()?
