Read Vcore Channel (ADC4) with USE TEMPERATURE BASED RADIO CALIBRATION active

Hello Carlos,

You did not mention how often you would like to check the voltage, or whether you have any specific constraints. Based on that, I would suggest considering these two options:

1. Use the existing adc_ctrl module
   This module is already available in your project for the temperature-based radio calibration. It also includes the ADCCTRL_RequestCoreVoltage function.
   If you would like to see an example of how it is used, you can look at the TEMPMEAS_RequestTemperatureMeasurement function, which periodically measures the temperature for calibration purposes.

2. Handle the ADC manually
   You can also manage the ADC yourself. In this case, you would need to include the temperature sensor reading in your ADC conversion sequence and store the measured value. Then, when the low-level (LL) driver requests the temperature value, you can simply return the stored value instead of starting a new ADC conversion at that moment.
   This approach gives you full control over the ADC while keeping the temperature measurement from affecting other ADC operations.

Please let me know if you would like to discuss either option further or if you have any additional questions.
