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

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

intended to be used.

The auxiliary interface needs to be enabled in UI_CTRL1_OIS (70h) / SPI2_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) / SPI2_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 Auxi_SPI 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) / SPI2_CTRL2_OIS (71h)).
