Can I connect my VREFC pin on my APEX II device to 1.5 V if I am not using a voltage referenced I/O Standard?

    Description

    Yes, you can connect the VREFC pin of a specific bank to 1.5 V if the VCCIO for that bank is 1.5 V, and the bank is not using a voltage-referenced I/O standard.

     

    In all other situations, you should connect the VREFC pin as described in the APEX II pin tables.
