1. When the gyroscope OIS or EIS chain is enabled, the LPF1 filter is not available in the gyroscope UI chain.

2. It is recommended to avoid using the LPF1 filter in mode1/2 when the gyroscope OIS or EIS chain is used.

3. When the gyroscope OIS is used, refer to the product application note for the power mode configuration and

settings.

The auxiliary interface needs to be enabled in UI_CTRL1_OIS (70h) / IF2_CTRL1_OIS (70h).

In mode 3 configuration, there are two paths:

•

The chain for user interface (UI) where the ODR is selectable from 7.5 Hz up to 7.68 kHz

•

The chain for OIS where the ODR is at 7.68 kHz and the LPF1 is available. The LPF1 configuration

depends on the setting of the LPF1_G_OIS_BW_[1:0] bits in register UI_CTRL2_OIS (71h) /

IF2_CTRL2_OIS (71h); for more details about the filter characteristics see UI_CTRL2_OIS (71h).

Gyroscope output values are in registers 22h to 27h if read from the auxiliary interfaces or in registers 2Eh

to 33h if read from the primary interface with the selected full scale FS_G_OIS_[1:0] bits in UI_CTRL2_OIS

(71h) / IF2_CTRL2_OIS (71h)).
