ADXL362 ODR and Measurement rate

I've been trying to figure out the maximum output data rate coming out of the ADXL362 and my results don't match up with the datasheet. The datasheet lists the max ODR as 400Hz but not matter how I configure it, the most I'm seeing is about 6Hz. I have a while loop that sits there and polls the status register, only reading when new data is available. My timer tells me that the DATA_READY bit is only set once every ~150millseconds regardless of what I set the ODR to. Is there something else I need to do to get the device to take measurements more frequently?

 

Thanks,
