Hi, it seems there is a typo in AN5755 at page 8 ch.4.2 it says: "Moreover, Qvar data can be stored in FIFO (by setting the QVAR_BATCH_EN bit to 1 in the COUNTER_BDR_REG1 (0Bh) register)". This statement doesn't apply to LSM6DSV16X, because it is not possible to redirect QVAR data out to FIFO. It applies only to LSM6DSV16BX at ch4.3.
regards
