I see several motion triggered FIFO data capture facilities. Can the IMU be configured to perform FIFO data capture based on an external interrupt?Is it possible to have an external interupt trigger data capture in the FIFO
Since the gyro needs to be in continous oscillation for measurement, and that it takes up to 80ms to spin-up, triggered MEMS gyroscope measurements are not really possible.
Your are correct that the status of the Interrupt pin can be sampled synchronous with the data sampling. See 18.104.22.168 FIFO synchronization with external events
