Hi Bosch Team,
I am facing an issue that ralates to accelerate FIFO. It seems like the data is correct enough all the time, but when I try to halt reading FIFO buffer for a while then the issue happens.

I mean "correct enough" because there is sometimes the data output is 0 on Y and Z and it's totally incorrect.
After halting the reading data from FIFO buffer, then read it back, the data is not correct anymore after hundred miliseconds

I can solve this issue by soft reset, load config file, set measurement config, etc...as the same at the first time I initialize the sensor.
But I do not prefer this approach and tried to reset FIFO by issue the set watermark command but it did not work.
The data is raw, mean LSB. Sensor is configured to water mark iterrupt = 200, ODR=12.5Hz, range=3g, extract 1 frame per time.
Any suggestion to find the root cause is appreciated.
Thanks and Regards
