How to get the acceleration sample corresponds to the exact time when the interrupt is triggered?

The LIS3DH is configured to use INT1 to interrupt the MCU when the acceleration value on any of the 3 axis exceed the threshold that is set by the MCU. Firstly, as my understanding, the LID3DH does not stop sampling acceleration data even if the interrupt is triggered (even in stream-to-fifo mode, it does not stop sampling until the fifo gets full). Is this correct? If it's correct, is there a good way to get the acceleration data corresponds to the exact time when the interrupt is triggered? Thanks.
