Hi, I'm working with a LSM6DSMTR device connected via I2C to a Nordic Semi nRF52382.  I would like to use the FIFO feature and have a question about the address rounding:

If I start the multiple data read at the FIFO_STATUS1 register and read 154 bytes, would that read the 4 bytes of status registers and 150 bytes of FIFO data?  Or does the first address have to be the FIFO_DATA_OUT_L register in order for the rounding to take effect?

    I think you can start with FIFO_STATUS1 it should work.
