45 / 212 page ![]() 6.9.1.2 Primary interface full control This option allows the application processor to configure all OIS functionalities from the primary interface. This option allows using embedded OIS data for both the main and front camera, connecting them to the application processor (eventually adding a context hub) as shown in Figure 27: the AP can also process the data before sending them to the cameras. In order to place the device in this mode, the OIS_CTRL_FROM_UI bit in the FUNC_CFG_ACCESS (01h) register must be set to 1 from the primary interface. Figure 27. OIS primary interface full control Context hub Front camera 6x UI/OIS AP I3C/SPI/I2C 2nd camera Main camera OIS driver Image sensor Actuator Context hub Front camera 6x UI/OIS AP I3C/SPI/I2C 2nd camera Main camera OIS driver Image sensor Actuator Auxiliary SPI / Auxiliary I3C (a) (b) Then, the AP can configure OIS functionalities through UI_INT_OIS (6Fh), UI_CTRL1_OIS (70h), UI_CTRL2_OIS (71h), UI_CTRL3_OIS (72h). By default, writing with the auxiliary SPI and writing/reading over the I3C are enabled. When the auxiliary SPI is used, the IF2_SPI_READ_EN bit in the UI_CTRL1_OIS (70h) register shall be set to 1. The IF2_SPI_READ_EN bit enables reading over the SPI interface and it also disables the auxiliary I3C interface (as shown in Figure 27 (b)). The auxiliary SPI can access the IF2_INT_OIS (6Fh), IF2_CTRL1_OIS (70h), IF2_CTRL2_OIS (71h), and IF2_CTRL3_OIS (72h) registers in read-only mode. Note: The OIS_CTRL_FROM_UI bit is reset by the software reset procedure. LSM6DSV320X Functionality DS14623 - Rev 1 page 45/212 |
