BF547  - Configuring SPORT0 Primary & Secondary to work with AD73311L x 4

I'm trying to work with SPORT0(Bf547) connected to four AD73311L. The primary ch' of the SPORT is connected to 2 AD73311Ls in cascade,and the secondary ch' of the SPORT is connected to the other 2 AD73311Ls.from an older code of mine (where I use only the Primary and only to codecs in cascade ), I took the control word that I send to the codecs ,and duplicate it(word for primary , word for secondary, and so on ).it seems like the codecs are not configured Properly . do you have any suggestions ? Any  insight? Any advices?

Thanks in advanced
