There is no connection on MCU_ADC0/1 signals in the SK-TDA4VM EVK schematics.
The datasheet says "Each of these balls must be connected to VSS through a separate external pull resistor to ensure these balls are held to a valid logic low level if unused."
Which one is correct?

There is a typo in the datasheet.
AB6 would have to be USB0_RCALIB.
