Strange problem on EMX module GPIO

I’m using an emx do develop my application in the first part of the code I have a problem, I can setup all pin as GPIO except for the IO75.
What’s the reason??

Tks


        public static void Main()
        {
            Stato = 0;
            HoldOn = new OutputPort(EMX.Pin.IO15, true);
            HoldOn.Write(true);

            oPompa = new OutputPort(EMX.Pin.IO9, false);
            oValvola = new OutputPort(EMX.Pin.IO16, false);

            oLedPompa = new OutputPort(EMX.Pin.IO30, false);
            oLedAria = new OutputPort(EMX.Pin.IO23, false);

            iPompa = new InputPort(EMX.Pin.IO75, true, Port.ResistorMode.PullUp);

            iBattLow = new InputPort(EMX.Pin.IO22, true, Port.ResistorMode.PullUp);

            iNoAC = new InputPort(EMX.Pin.IO20, true, Port.ResistorMode.PullUp);

what happens?

Only interrupts pins can use glitch filter. Try it with false.
