ADS8688: ADC is passing the input -but SPI is not getting the data

Part Number: ADS8688

Tool/software:

adc_voltage.zip

Dear ST

I am encountering an issue with our current setup involving an Analog-to-Digital Converter (ADC) and a Microcontroller Unit (MCU).

The ADC is successfully receiving  the input voltage when measured directly at its pins. However, the MCU connected to the ADC does not appear to be reading this voltage data. Consequently, I am unable to visualize the voltage output in our software interface.in ADC i cannot able receive Ref voltage 4.596 v in my board

Here are some details that might be helpful:

ADC Model: [ADS8688IDBTR]

MCU Model: [STM32G0B1VET6]

Connection Method: [SPI]

Software/Firmware Used: [STM CUBEIDEA 1.12.1}

Observed Behavior: The ADC shows the correct voltage, but the MCU's readings (when debugging or trying to output) are consistently zero or incorrect, and no data is reflected in the visualization software.

Troubleshooting Steps Taken So Far:

Confirmed voltage at ADC input pins using a multimeter.

confirmed voltage at ADC in ref voltage is not coming as 4.569.

Checked physical connections between ADC and MCU for continuity.

Verified power supply to both ADC and MCU.

Could you please provide some guidance or assistance in diagnosing and resolving this issue? I suspect it might be related to [mention].
