The recommended power-on sequence is to first apply VDDIO, then VDD, and finally enable the sensor by setting the ON bit in the command register.
The interrupt pins can be configured through the INT1 and INT2 registers. The interrupt sources can be selected through the INT_CFG register, and the interrupt pins can be configured as push-pull or open-drain through the INT_PIN_CFG register.
The self-test feature is used to verify the functionality of the sensor. It applies a known stimulus to the sensor and checks the output to ensure it is within the expected range. This feature can be used during production testing or in the field to verify the sensor's operation.
The acceleration values can be calculated by multiplying the raw data output by the sensitivity scale factor, which is dependent on the full-scale range selected. The sensitivity scale factor can be found in the datasheet.
The low-power mode reduces the power consumption of the sensor by reducing the bandwidth and increasing the noise. The low-noise mode, on the other hand, reduces the noise of the sensor by increasing the bandwidth and power consumption. The choice of mode depends on the specific application requirements.
