1. When Mode3/4 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 Mode3/4 is intended to be used.
3. HP_EN_OIS can be used to select the HPF on the OIS path only if the HPF is not used in the UI chain. If
both the HP_EN_G bit and HP_EN_OIS bit are set to 1, the HP filter is applied to the UI chain only.
The auxiliary interface needs to be enabled in CTRL1_OIS (70h).
In Mode 3/4 configuration, there are two paths:
the chain for User Interface (UI) where the ODR is selectable from 12.5 Hz up to 6.66 kHz
the chain for OIS/EIS where the ODR is at 6.66 kHz and the LPF1 is available. The LPF1 configuration
depends on the setting of the FTYPE_[1;0] _OIS bit in register CTRL2_OIS (71h); for more details about the
filter characteristics see Table 151. Gyroscope OIS chain digital LPF1 filter bandwidth selection. Gyroscope
output values are in registers 22h to 27h with the selected full scale (FS[1:0]_G_OIS bit in CTRL1_OIS
(70h)).
