Hi,
Seems in your scopes that your master is generating a STOP condition after you write the 0x0D register (WHO AM I register), then a START condition for the read, I’m not sure if the MMA8452 can handle this, please try to send a REPEATED START condition instead of this STOP/START condition.
Regards,
