ODR_FIFO_[3:0]

FIFO ODR selection, setting FIFO_MODE also. Default: 0000

For the configuration setting, refer to Table 39

FIFO_MODE_[2:0]

FIFO mode selection bits, setting ODR_FIFO also. Default value: 000

For the configuration setting refer to Table 40

Table 39. FIFO ODR selection

ODR_FIFO_[3:0]

Configuration(1)

1. If the device is working at an ODR slower than the one selected, FIFO ODR is limited to that ODR value.

Moreover, these bits are effective if both the DATA_VALID_SEL FIFO bit of MASTER_CONFIG (1Ah) and

the TIMER_PEDO_FIFO_DRDY bit of FIFO_CTRL2 (07h) are set to 0.

Table 40. FIFO mode selection

FIFO_MODE_[2:0]

Configuration mode

000

Bypass mode. FIFO disabled.

001

FIFO mode. Stops collecting data when FIFO is full.

010

Reserved

011

Continuous mode until trigger is deasserted, then FIFO mode.

100

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.
