ADS7828-Q1: I2C interface issue

Part Number: ADS7828-Q1
Other Parts Discussed in Thread: ADS7828

Hi,

I'd like to ask you I2C interface issue that slave device(ADS7828-Q1) outputs a NACK signal on the SDA line after MCU(Master) transmits Address byte(10010000). My customer wants to know the reason why. Is there any check points to resolve this issue? Please refer to the attached file below. Also, Is there any application example codes that have a sequence of initialization, start, command transmit & data receive, and data processing. Please share it with me if you have the related codes or document.
