 That file also includes the definition for the ```icm_20948_DMP_data_t``` struct which is loaded with DMP data from the FIFO.

 ## Can the DMP generate interrupts?
 
 Yes it can, but you might find that they are not fully supported as we have not tested them. The main functions you will need to experiment with are ```intEnableDMP``` and ```enableDMPSensorInt```.
 
 ## How is the DMP data rate set?
 
-We don't know the complete answer to this. As we understand it, it is a _combination_ of the raw sensor rate (set by ```setSampleRate```) and the multiple DMP Output Data Rate (ODR) registers
-(set by ```setDMPODRrate```). The documentation says that the "DMP is capable of outputting multiple sensor data at different rates to FIFO". So, in theory, you can have (e.g.) raw accelerometer
-data and Quaternion data arriving at different rates, but we have not tested that.
+It is a _combination_ of the raw sensor rate (set by ```setSampleRate```) and the multiple DMP Output Data Rate (ODR) registers
