LSM6DS3H
9.52
FIFO_STATUS1 (3Ah)
FIFO status control register (r). For a proper reading of the register it is suggested to set BDU bit in
CTRL3_C (12h) to 0.

Table 138. FIFO_STATUS1 register description
DIFF_FIFO_[7:0] Number of unread words (16-bit axes) stored in FIFO⁽¹⁾.
1. For a complete number of unread samples, consider DIFF_FIFO [11:8] in FIFO_STATUS2 (3Bh)
9.53
FIFO_STATUS2 (3Bh)
FIFO status control register (r). For a proper reading of the register it is recommended to set the
BDU bit in CTRL3_C (12h) to 0.

Table 140. FIFO_STATUS2 register description
FTH
FIFO watermark status. Default value: 0
(0: FIFO filling is lower than watermark level⁽¹⁾;
1: FIFO filling is equal to or higher than the watermark level)
FIFO_OVER_RUN FIFO overrun status. Default value: 0
(0: FIFO is not completely filled; 1: FIFO is completely filled)
FIFO_FULL
FIFO full status. Default value: 0
(0: FIFO is not full; 1: FIFO will be full at the next ODR)
FIFO_EMPTY
DIFF_FIFO_[7:0]
FIFO empty bit. Default value: 0
(0: FIFO contains data; 1: FIFO is empty)
Number of unread words (16-bit axes) stored in FIFO⁽²⁾.
1. FIFO watermark level is set in FTH_[11:0] in FIFO_CTRL1 (06h) and FIFO_CTRL2 (07h)
2. For a complete number of unread samples, consider DIFF_FIFO [11:8] in FIFO_STATUS1 (3Ah)
