What is the exact TDM mode that is supported by the ASRCs

I have been trying to set up the ASRCs to convert an incoming 8 channel TDM stream of audio from one sample rate to another.  I have the incoming TDM stream running into a SPORT and being decoded into 8 audio channels.  At the same time I'm running the stream into the ASRCs to try to convert it.  The SPORT has a lot of options (i.e. CKRE, LFS, etc bits in the SPCTL registers) to know how to decode the TDM stream properly.  The ASRCs have none of these options, which leads me to believe it only supports a specific combination of options to SRC the TDM stream.  So, does anyone know this supported TDM configuration?  I am using a SHARC 21488.
