AD7676 interface to ADSP-2136x

In EE248 and in the attached SW it says that "the SPORT must be configured initially for a serial word length of 15 bits".

After reading two words from AD7676 the word length is then modified on-the-fly to 16 bits.

There's not given any explanation why this is done, it's just "for the interface to work properly"!!

Is this an anomaly of the AD7676 or the ADSP-2136x processors or what's the reason for this?

I'm using AD7610 and ADSP-21369 and wonder if I will need to do similar tricks?

 

I also posted the question in the "Precision ADC's" forum:

and there it was beleived that this is a processor issue?
