DAC34H84: Interfacing all four channels of DAC 34H84 through xilinx FPGA FMC adapter

Part Number: DAC34H84

I am trying to use all four channel A,B,C,D of DAC34H84, In DAC34H84 datasheet page 26, the Data Transmission format is given in which the inputs are labeled as "DAB" and "DCD" while in FMC Adaptor the inputs are "DXX" and "DBXX",

should I consider inputs "DAB" = "DXX" and "DCD" = "DBXX" or there is something that I got it wrong?
