Hi Eranga,
Unfortunately, as there is no Device Driver available for CrossCore Embedded Studio, you would have to directly interact with the codec through the SPORT interface. Do you still have VisualDSP++ installed? If so, take a look at the Power On Self Test example for the BF548 EZ-KIT Lite.
Within the folder "...\Blackfin\Examples\ADSP-BF548 EZ-KIT Lite\Power_On_Self_Test\" you will see a file called "Audio_test.c". This demonstrates how to enable and configure the codec, test a transmit and receive buffer, etc, all using direct register access, rather than a device driver. This could be ported to CCES, and adapted for audio processing (rather than just testing its very small buffers).
Regards,
Craig.
