ADAU1966 Audio DAC documentation for I2C seems all messed up

I am looking through the datasheet for the ADAU1966 audio DAC trying to get I2C working but there seems to be a lot of errors in the datasheet.

 

For example, on page 17 it references Rb/W being low for the first address frame but the nomenclature in the diagram on page 18 shows R/Wb. I assume R/Wb is really the intent (as per the I2C specification).

 

Next, on page 18 figure 13 for a read shows the AD0/AD1 bits being in the MSB positions for the first chip address cycle (frame 1) but in the LSB positions for the second address cycle (frame 3). I don't think this is correct.

 

I am still trying to get my code working correctly since my current implementation does not do repeated starts, so I am adding this, but I wanted to get some feedback on what the correct address control bit positions are for read operations?

 

BR,

Steve
