6.5.1.3

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 23. The AP can also do some processing on 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)

Then, the AP can configure OIS functionalities through UI_INT_OIS (6Fh), UI_CTRL1_OIS (70h), UI_CTRL2_OIS

(71h), UI_CTRL3_OIS (72h).

The OIS_EN_SPI2 bit in the UI_CTRL1_OIS (70h) register enables the gyroscope OIS chain.

Reading from the auxiliary SPI can be enabled by setting the SPI2_ READ_EN bit in the UI_INT_OIS (6Fh)

SPI2_INT_OIS (6Fh), SPI2_CTRL1_OIS (70h), SPI2_CTRL2_OIS (71h), and SPI2_CTRL3_OIS (72h) registers

in read-only mode.

Note:

If the accelerometer ultralow-power mode is active when activation of the OIS is required, the device must be set

in power-down mode before enabling the OIS chain.

Note:

The OIS_CTRL_FROM_UI bit is reset from the software reset procedure.
