AD7606 Connections to ADSP-BF547 EPPI

After studying chapter 7 of the Hardware Reference Manual at:

http://www.analog.com/static/imported-files/processor_manuals/ADSP-BF54x_HRM_rev1.0.pdf

and the AD7606 Spec Sheet

http://www.analog.com/static/imported-files/data_sheets/AD7606_7606-6_7606-4.pdf

My understanding of the above is that the below connections are the ones to make where conversion data is to be read by the processor DMA, the conversions are to be triggered at regular intervals by the processor, data is 16 bit parallel, and the AD7606 is the only device on the EPPI port. Comments on the correctness of these connections would be much appreciated. I cannot afford to make a mistake here:
