    [AN65974] Why the PMODE is configured as output and set to b11 in slaveFIFO2b_fpga_top.v

      It  creates this hassle described in the app note:


      The FX3 DVK should be programmed before programming the Xilinx FPGA board. The FX3 DVK will not enumerate on the host PC if the FPGA has already been programmed, because it drives the PMODE lines


      I don't want to disconnect the FPGA each time I program FX3, can simply I change the PMODE to be the input?
