Once the FPD-Link III setup is done for the DS90UB953-Q1 and DS90UB960-Q1 devices, the I2C initialization can now be done on the AR0820. For these writes, see the AR0820 data sheet for register settings. There are many register settings listed to configure both the imager and ISP, but as long as the DS90UB953-Q1 and DS90UB960-Q1 FPD-Link III parts are configured, the I2C back channel allows for the AR0820 to be accessed at address 0x10. For this testing, the AR0820 is configured for RAW12 HDR output at 3840 × 2160 resolution.
