Hello, our customer try to communicate the MMA8653FC via I2C, and they try to read the chip ID(register address: 0x0D), it can'r send back the right value. We testt the SDA and SCL waveform. We found the ACK signal is abnormal. Enclosed the SDA AND SCL waveform. Do you know what's wrong with it?

 

Thanks!
