Table 36. FIFO_CTRL4 register description

DEC_TS_BATCH_[1:0]

Selects decimation for timestamp batching in FIFO. Write rate is the maximum rate between the

accelerometer and gyroscope BDR divided by decimation decoder.

(00: timestamp not batched in FIFO (default);

01: decimation 1: max(BDR_XL[Hz],BDR_GY[Hz]) [Hz];

10: decimation 8: max(BDR_XL[Hz],BDR_GY[Hz])/8 [Hz];

11: decimation 32: max(BDR_XL[Hz],BDR_GY[Hz])/32 [Hz])

ODR_T_BATCH_[1:0]

Selects batch data rate (write frequency in FIFO) for temperature data

(00: temperature not batched in FIFO (default);

01: 1.875 Hz;

10: 15 Hz;

11: 60 Hz)

G_EIS_FIFO_EN

Enables FIFO batching of enhanced EIS gyroscope output values. Default value: 0

(0: disabled; 1: enabled)

FIFO_MODE_[2:0]

FIFO mode selection

(000: bypass mode: FIFO disabled (default);

001: FIFO mode: stops collecting data when FIFO is full;

010: continuousWTM-to-full mode: continuous mode with FIFO watermark size until trigger is

deasserted, then data are stored in FIFO until the buffer is full;

011: continuous-to-FIFO mode: continuous mode until trigger is deasserted, then FIFO mode;

100: bypass-to-continuous mode: bypass mode until trigger is deasserted, then continuous mode;

101: reserved;

110: continuous mode: if the FIFO is full, the new sample overwrites the older one;

111: bypass-to-FIFO mode: bypass mode until trigger is deasserted, then FIFO mode.)
