ADPD105 FIFO data packet format

Question

What is the data format of the samples stored in the FIFO for both slots enabled (same ODR) and 32-bit mode? 
 I haven't been able to decipher the format of the data stored in the FIFO from the datasheet or code examples. Attached is the configuration I am using for the WaveTool and a saved configuration. 
 A detailed description of the FIFO data packet format (data packet is the terminology used on pg 33. of the datasheet RevA) for 16-bit and 32-bit configurations would be useful. The configuration below is for 32-bit, 4 channels. 
 Are the samples stored in the FIFO big endian? Are the sample stored in slot A: channels 1,2,3,4, then slot B: channels 1,2,3,4? Or is the format similar to registers 0x70-0x7F?

Hello, 
 The samples will be stored in the FIFO timeslot A, CH1 then 2 then 3 then 4 followed by timeslot B CH1 then 2 then 3 then 4. If the device is storing data in 16b mode, the first byte to come out is the [15:8] byte followed by the [7:0] byte. In 32b mode the data will come out as follows: [15:8] then [7:0] then [31:24] then [23:16].
