TDA7419 I2C register read-back does not work

I am trying to read back I2C registers on the TDA7419 audio processor to verify their contents.  I've try both standard I2C register reads as well as the custom method on Page 29 of the datasheet (rev7).  In all cases, a NACK is received and no data is transmitted.

 

Does register read-back work on the TDA7419.  If so, does anyone have an explicit timing diagram?

 

Thanks!
