BHI360: NoMotion ODR depedency

Hello!

We are using the BHI360 in a low power application with NoMotion Interrupts enabled. We are seeing an issue with the Duration of the NoMotion interrupt. If the accelerometer is not enabled explicitly the sensor seems to only sample with an ODR of 12.5Hz compared to the 50Hz stated in the datasheet for the NoMotion duration samples. If enabling the accelerometer the interrupt duration no matches the configured one.

For example: 4sec NoMotion timeout results in 4sec timeout with accelerometer enabled and 16sec with accelerometer disabled.

How is the ODR internally set? Is there a way to read/set the ODR value manually?
