ADSP-21477 how routing SPORTs in SRU matrix

Hi all,
I have to develope a project using the ADSP-21477 and I'm checking the DSP's pinout, in my application I have to connect all the SPORT to the FPGA.
I read the documents: "ADSP-214xx SHARC® Processor Hardware Reference" and "Configuring the Signal Routing Unit of ADSP-2126x SHARC® DSPs (EE-232)" to understand how pin routing works in SRU matrix.

 

Datasheet tells that the SPORT signal are routed on DAI pins (as shown by Figure 1 of datasheet) but if I have 20 DAI pins how I can map 8 SPORT interface (4x8=32 pins)?

 

Thanks.
