Block diagrams of the accelerometer filters
In the LSM6DSL, the filtering chain for the accelerometer part is composed of the following:
 Analog filter (anti-aliasing)
 Digital filter (LPF1)
 Composite filter
Details of the block diagram appear in the following figure.

The configuration of the digital filter can be set using the LPF1_BW_SEL bit in CTRL1_XL
(10h) and the INPUT_COMPOSITE bit in CTRL8_XL (17h).
