Hello experts,
I am working on i.MX93 ADC and trying to read ADC using cortex-m33 mcu. In that I have checked almost all the registers related to ADC but unable to find Vref selection or configuration related register.
1. Here what I want to know is that what is the voltage value of my Vref ?
2. How this Vref is selected by ADC, is there any dedicated register available to set Vref ?
P.S: I am able to read ADC value from PCDR register but just confusion is that how vref is selected by ADC.

Hello,
Yes, that it correct.
To use SAR ADC, a calibration/self-test must be performed after every power-up reset. This will check the supply voltage, reference voltage and calibrated values to warranty a correctly functionality.
Best regards.
