In Low-power mode and Normal mode, the BW is equal to ODR/2 which is understandable. But in HR mode, the BW is ODR/9, why?

For high resolution, there is a filter inside the sensor which decrease the BW.

Thanks for the reply. To make sure, the filter you mentioned is only applicable for high resolution mode, thus is a totally different filter than the High-Pass filter which is common for all modes, right?

Yes, you are right.
