LSM6DSV16X: Inactivity sleep duration values discrepancy between "LSM6DSV16X" & "AN5763"

Hi,

My question is in regard with SLEEP_DUR of the register WAKE_UP_DUR.

Datasheet "LSM6DSV16X" (p98) mentions:
Duration to go in sleep mode. Default value: 0000 (this corresponds to 16 ODR) 1 LSB = 512/ODR_XL time"

Whereas the "AN5763" (p60) instead specify:
SLEEP_DUR_[3:0] bits of the WAKE_UP_DUR register: 1 LSB corresponds to 514 / ODR_XL time, where ODR_XL is the accelerometer output data rate. If the SLEEP_DUR_[3:0] bits are set to 0000, the duration of the inactivity state to be recognized is equal to 18 / ODR_XL time.

Not that the very similar specs impact product design itself, however I would prefer to know the correct one.

Thank you,
