Gyroscope digital chain - Mode 3 / Mode 4 (OIS/EIS) ADC Digital HP Filter HP_EN_G 0 1 HP_EN_OIS Digital LP Filter FTYPE[1:0]_OIS LPF1 1 0 SPI / I2C / MIPI I3CSM FIFO Digital LP Filter ODR_G[3:0] LPF2 ODR Gyro @6.6 kHz (1) (2) (3) (3) SPI_Aux / SPI / I2C / MIPI I3CSM 1. When Mode 3/4 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. Note: When S4S is enabled in the UI chain, the HPF is not available in the OIS chain. The auxiliary interface needs to be enabled in UI_CTRL1_OIS (70h) / SPI2_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 UI_CTRL2_OIS (71h) / SPI2_CTRL2_OIS (71h); for more details about the filter characteristics see Table 182. Gyroscope OIS chain digital LPF1 filter bandwidth selection. Gyroscope output values are in registers 22h to 27h if read from the Auxi_SPI or in registers 4Ah to 4Fh if read from the primary interface with the selected full scale (FS[1:0]_G_OIS bit in UI_CTRL1_OIS (70h) / SPI2_CTRL1_OIS (70h)).
