Hello,

 

I am using ADSP-BF533 Processor. I need to connect to DAC and ADC using SPORT. I am trying to understand the SPORT concepts but I have few doubts regarding the same.

I have attached the block diagram for reference.

 

DSP is at 40Mhz, SCLK is 5MHz and TSCLK1 at 1Mhz.

 

I need to know how SPORT wil be used for transmitting and receiving data between DSP and ADC. As the CS is active low input, only TFS1 can be used for tramitting data. What about the RFS1? How will that be used for reading data?

 

Please Help.. Looking forward for the reply.
