AD7327: Control setting and Conversion Data read for "Fully Differential Input Mode" and "Pseudo Differential Input Mode"

Hi,

Couple of queries on AD3727

1. For setting 8 inputs as "4 Fully Differential Inputs" (Mode 1 = 1, Mode 0 = 0) or "4 Pseudo Differential Inputs" (Mode 1 = 0, Mode 0 = 1) whether user has to write 8 times Control Word with appropriate ADD2, ADD1 and ADD0 and corresponding mode bits or 4 times with ADD2:1 = 0, 3,4,7? Why i asked this question is that, if Mode is selected as AD, the analog inputs are fixed for ADD (0 and 1 ) or (2 and 3) or (4 and 5) or (6 and 7). 

2. Similarly what the Channel Identification number in DOUT while inputs configured Fully Diff or Pseudo Diff? 

with regards
