Dear experts,

does the KV10 support alternate reference inputs for the ADC? The VALTH, VALTL pins are not documented in the KV10 datasheet. What happens when ADCx_SC2[REFSEL] is set to 01b? The sub-family reference states the behavior is device-dependent. However, I cannot find any details related to the KV10 MCU. Could you please provide this piece of information?

Thanks in advance for your consideration

The VATL reference can be found at section 3.8.1.6 of the KV10 reference manual. For this MCU the alterante voltage is internally connected to the VDDA reference.
