BF592 use of both SPORTs

With the BF592, can I connect one SPORT to a multichannel codec CS42438 with TDM interface and the other to a Cirrus AES/EBU receiver ?

The codec would always receive clock from the Blackfin. If AES/EBU was present the Blackfin would receive clock from the AES/EBU receiver , otherwise it would provide local clock.

The reason I ask is the part in the datasheet that says:

" Each of the serial ports can work in conjunction with

another serial port to provide TDM support. In this configura-tion, one SPORT provides two transmit signals while the other

SPORT provides the two receive signals. The frame sync and

clock are shared."

 

which confused me.... the rest of the data suggest the SPORTS are TX/RX and independent
