One thing I'd like to mention that the ODR range for performance is from 12.5 to 1600, and the ODR range for low power mode is from 0.78 to 400.
No motion and any motion should work in low power mode as well, but you should consider how it works.
Regarding any motion, the idea is if the data is over the threshold and it keeps over duration, any motion interrupt is generated.
No motion is vice versa.
If ODR is slow, it takes longer time for duration therefore you have to modify duration value.
If you are using github API, you can check in bma456h_feature_enable.
BMI270 datasheet has detailed information about anymotion and nomotion.
Please let me know if you have any quesitons.
