This solution will help for now.

private static double ReadDeviceTemperature() { channel = controller.OpenChannel(SC20260.Adc.Controller3.InternalTemperatureSensor); // GHI added

        int disable_val = Marshal.ReadInt32(enable_reg);

        int enable_val = disable_val |= (1 << 23);

        Marshal.WriteInt32(enable_reg, enable_val);

        var v = channel.ReadValue() * 1.0;

        var ts1 = Marshal.ReadInt32(ts_reg1);
        var ts2 = Marshal.ReadInt32(ts_reg2);

        Marshal.WriteInt32(enable_reg, disable_val);

        var t1 = (110 - 30) * 1.0;
        var t2 = (ts2 - ts1) * 1.0;
        var t3 = (v - ts1) * 1.0;

        double temperature = t1 / t2 * t3 + 30;

        Debug.WriteLine("T = " + temperature + " Celsius");

        channel.Dispose();  // GHI added

        return temperature;
    }

Done. Correct analog touch then this issue gone.
