1. This bit must be set to ‘0’ for the correct operation of the device.
Table 38. FIFO_CTRL5 register description
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

FIFO ODR is set to 208 Hz

FIFO ODR is set to 833 Hz
FIFO ODR is set to 1.66 kHz

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.
