ADAU1701 I2C read

Hi

 

My customer is trying to initiate an i2c read from adau1701.

Addr0==Addr1=0 => Write addr = 0x68, Read addr = 0x69.

Sequence looks like he indeed sends 0x69, however adaqu1701 doesn't send an ack (pulls SDA low on 9th clock)

Attached are read sequence & schematics.

 

Similar write sequence (sending 0x68)  produces the required ack.

 

Please advise

 

BR,

Alon
