BQ40Z50-R2: BQ40Z50-R2 when simulating SMBus communication, data anomalies occasionally occur.

Hi 

I have a query need your help.

Use CRC-PEC to calculate the check digit, and the result is the same as the last digit of the read data, indicating that there is no interference during data transmission. The frequency is 50KHz.

SMBus requires clock stretching for the slave device to prepare data. Is this clock stretching controlled by the slave device on SCL?

Waiting for your reply.

Thanks
