    Hi Carlo,

    Thanks for your question.

    Pin 46 is different depending on the package. There are 2x different 64-pin packages available:

    As you can see in the pin attributes, VREGENZ is only available on PMQ package. GPIO39 (and all of the associated other signals like EQEP, etc.) are not available on the PMQ package:

    So answering your question:

    No, this is not possible.
