FSM compatibility with SFLP or tap detect in LSM6DSV?

I have four FSM programs working with the LSM6DSV sensor, all set to AODR/GODR of 30Hz in line with the examples I copied. Tap detect requires significantly higher ODR.  I might also want to run the SFLP at a rate higher than 15 or 30 Hz, so does this mean that I can't run the FSM when running the AODR/GODR at higher rates than 30 Hz or that I simply need to change the FSM program configuration (gulp!) to account for the desired higher rates?

Hi @KWine ,

Each feature runs at the ODR selected for that feature (the important thing is to set XL / Gyro ODR properly), furthermore each FSM allows a decimation factor to be applied to run the specific program at FSM_ODR / decimator.

Would you mind specifying which register has the FSM_ODR decimator please?

Nevermind, I see it. Section 7.6 in AN5907.
