FIFO_STATUS2 (3Bh)

FIFO status register 2 (r)

Table 114. FIFO_STATUS2 register description

9.40

TIMESTAMP0 (40h), TIMESTAMP1 (41h), TIMESTAMP2 (42h),

and TIMESTAMP3 (43h)

Timestamp first data output register (r). The value is expressed as a 32-bit word and the bit

resolution is 25 μs.

FIFO_

WTM_IA

FIFO watermark status. Default value: 0

(0: FIFO filling is lower than WTM;

1: FIFO filling is equal to or greater than WTM)

Watermark is set through bits WTM[8:0] in FIFO_CTRL2 (08h) and FIFO_CTRL1

(07h).

FIFO_

OVR_IA

FIFO overrun status. Default value: 0

(0: FIFO is not completely filled; 1: FIFO is completely filled)

FIFO_

FULL_IA

Smart FIFO full status. Default value: 0

(0: FIFO is not full; 1: FIFO will be full at the next ODR)

COUNTER_

BDR_IA

Counter BDR reaches the CNT_BDR_TH_[10:0] threshold set in

COUNTER_BDR_REG1 (0Bh) and COUNTER_BDR_REG2 (0Ch). Default value: 0

This bit is reset when these registers are read.

FIFO_OVR_

LATCHED

Latched FIFO overrun status. Default value: 0

This bit is reset when this register is read.

DIFF_

FIFO_[9:8]

Number of unread sensor data (TAG + 6 bytes) stored in FIFO. Default value: 00

In conjunction with DIFF_FIFO[7:0] in FIFO_STATUS1 (3Ah)
