Hi Sean,
Section 60.2.2 Features of the S32K3XXRM states:
•Selectable resolution (8-, 10-, 12-, 14-bit). Note that the conversion result is always 15 bits wide, even if the selected resolution is smaller (see CALBISTREG[RESN]).

S32K3 DataSheet states: TUE spec for precision and standard channels is based on 12-bit level resolution.
If you set the resolution to 14-bit, the TUE is only slightly better than that of 12-bit resolution.
Best Regards,
Robin
