    INT#/CTL[15] handling?




      Due to a PCB issue, I need INT#/CTL[15] either fixed to 0.0 V or high impedance. Currently, I did not do anything with it and it drives an intermeidate level of 1.5 V.


      From the technical reference manual (Spec No.: 001-76074 Rev. *B), I learn "The INT# pin can be configured to indicate the presence of FX3 in low-power mode" so I assume that it can actually be configured. But how?

          Hey Peter


          The INT# pin can be configured to proper level using the GPIF project. While designing the GPIF project, you can add one more output signal and assign it to the INT# pin. You set the state of that pin the GPIF state machine. Please try!
