LSM6DSM fifo pattern error

[Dilbert K]

I am using the FIFO to read both the ACC & GYRO data using the FIFO_DATA_OUT_H and FIFO_DATA_OUT_L at 52Hz ODR.

But once every 1~2 hours, the FIFO data seems corrupted. Debugging it shows the FIFO Pattern number (FIFO_STATUS3 & FIFO_STATUS4) return a huge number like (0x1D8).

The normal case, Pattern should be 0~5 for GYRO-ACC.

Anyone experience this issue before ?
