I use I2C betweeb MCU and AD5392.

I set AD0=1,AD1=1 in the circuit and send 10101110 from MCU , but AD5392 does NOT reply ACK

Please refer to the attached screenshot.

And I attach the power sequence timing diagram with DVDD,AVDD waveform.

would you teach me what is wrong with my setting?

Does this power sequence have any potential problem?

Please send me your advice.
