OIS

This paragraph describes OIS functionality and dedicated accelerometer-gyroscope DSP chain.

There is a dedicated gyroscope and accelerometer DSP for OIS.

Other features can be configured:

•

Self-test on OIS side

•

DEN on OIS side

6.5.1

Enabling OIS functionality and connection schemes

There are three different ways in order to enable and configure OIS functionality:

•

Auxiliary SPI full-control: enabling and configuration done from auxiliary SPI

•

Enabling primary interface: enable from primary interface, configuration from auxiliary SPI

•

Primary interface full-control: enabling and configuration done from primary interface

The configurations that allow selecting these three different options are done using the OIS_CTRL_FROM_UI bit

in FUNC_CFG_ACCESS (01h) and the OIS_ON_EN bit in CTRL7_G (16h) as described in the following table.
