BQ27Z561: I2C waveform check

Part Number: BQ27Z561

Tool/software:

Hi Team, 

I'm reaching out to seek your expertise regarding the MCU access fuel gauge(BQ27Z561) waveform. Specifically, I've noticed that the SDA output precedes the CLK. Additionally, there appears to be an abnormal SDA signal output.

 

Could you please help clarify whether the waveform in question is normal or abnormal?

 

Thank you in advance for your assistance.
