I have configured the registers as per the datasheet. I get interrupts at every sample interval rather than when there is motion. It seems as though instead of wake-on-motion the data-ready interrupt is enabled. I have verified all the register have the correct values.
I migrated to this part from the ICM-20602 which used a very similar wake-on-motion initialization process and it worked fine.
Any suggestions as to what I may be missing?
