SPORTs Synchronization in SHARC EE-377 Talkthrough Example Code

I'm looking into the source of the EE 377 Audio Talkthrough example and I read in the paper:


The SPORT allocated to SHARC #2 is synchronized with the SPORT allocated to SHARC #1 during
initialization. After the MDMA completion interrupt occurs, SHARC #2 has almost one whole frame worth
of time before its SPORT callback function expects another frame.


I cannot find the part of the code that synchronizing SPORT of SHARC #2 to SPORT of SHARC #1. Can anyone point me to the part of code that ensures this synchronization is done? I've looked in Adau1962Interface.c file but couldn't find this.


Thanks a lot!
