Reading data of LTC2122 ADC


I am using FPGA to acquire data from LTC2122. It is a 14 bit ADC but it receives some 16 bits per channel. 

No I want to extract the data bits . Please guide me which 14 bits should I consider for data and which two bits are status or the OF bits( I cant much understand from datasheet)

the ADC is working in the range of 0-5 V

Best Regards
