UI chain

Note: Mode 4 is enabled when Mode4_EN = 1 and OIS_EN_SPI2 = 1 in CTRL1_OIS (70h).

The configuration of the accelerometer UI chain is not affected by enabling Mode 4.

Accelerometer output values are in registers OUTX_L_A (28h) and OUTX_H_A (29h) through OUTZ_L_A (2Ch)

and OUTZ_H_A (2Dh) and ODR at 6.66 kHz.

Block diagrams of the gyroscope filters

In the LSM6DSR, the gyroscope filtering chain depends on the mode configuration:

•

Mode 1 (for User Interface (UI) and Electronic Image Stabilization (EIS) functionality through primary

interface) and Mode 2

In this configuration, the gyroscope ODR is selectable from 12.5 Hz up to 6.66 kHz. A low-pass filter (LPF1) is

available if the auxiliary SPI is disabled, for more details about the filter characteristics see Table 65. Gyroscope

LPF1 bandwidth selection.

The digital LPF2 filter cannot be configured by the user and its cutoff frequency depends on the selected

gyroscope ODR, as indicated in the following table.
