AD9747 DPG2 Evaluation Board

PCB Name: AD9747 DPG2 Evaluation Board
PCB Part Number: AD9747-DPG2-EBZ

We have connected system board Nexys 2 Spartan-3E FPGA Board from  Digilent to AD9747 DPG2 Evaluation Board from Analog Devices.

Unfortunately this connection is executed in such a manner that I cannot  use a mode single-port.
Besides, at mode use dual-port bits P1D<7:0> and P2D<7:0> are accessible  to me only.
Thus not used signals of ports of the data remain not connected (floating).

Question. It is possible to use ADC AD9747 in such mode when some bits  of ports of data P1D or P2D appear not connected (floating)?
