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

(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)

FIFO_STATUS3 (3Ch)

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.
