How to read data from ADC in FMCOMMS2

Hi all,


I am using FMCOMMS2 with zedboard. I understood that the DAC is 12-bit so when we make he data accessible to adc the last 4 bits from the 16-bits memory aligned are ignored in DAC. Now I want to read data back from ADC. I capture data with adc_capture() function and save them in DDR location. How should I read these data!? Should I ignore the last 4 bits in every 16 bits or I have to read with 12 bits step every single bit without ignoring anything!?


Any help would be appreciated.
