    Hello @YFANG.2 

    As you can see on the DS13086:

    "VREF- and VREF+ pins are not available on all packages. When not available, they are bonded to VSSA and VDDA, respectively. 

    When the VREF+ is double-bonded with VDDA in a package, the internal voltage
    reference buffer is not available and must be kept disabled."
