About I2C format on ADAU1977(DAC)

Hello all,


I have a question about I2C format between ADAU1977(ADC)and ADSP21489(DSP)


I am looking at a Figure 22-11. Transmit/Receive Data Repeated Start on HRM of SHARC

and Figure 39. Single-Word I2C Read Format on Data Sheet of the ADC


ADAU1977's format is missing an acknowledgement at the end on figure 39.

Is this misprint? or are you intended so?


I would like to ask you if I can do a master read between master SHARC and slave ADC.


Thank you very much.
