9.51 SENSORHUB12_REG(39h)
Twelfth byte associated to external sensors. The content of the register is consistent with the
SLAVEx_CONFIG number of read operation configurations (for external sensors from x = 0 to x = 3).
9.52 FIFO_STATUS1 (3Ah)
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 1.

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 1.

FTH FIFO watermark status. Default value: 0

;
1: FIFO filling is equal to or higher than the watermark level)
1. FIFO watermark level is set in FTH_[11:0] in FIFO_CTRL1 (06h) and FIFO_CTRL2 (07h)
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 FIFO empty bit. Default value: 0
(0: FIFO contains data; 1: FIFO is empty)
DIFF_FIFO_[7:0] Number of unread words (16-bit axes) stored in FIFO
(2)
.
2. For a complete number of unread samples, consider DIFF_FIFO [11:8] in FIFO_STATUS1 (3Ah)
