3.14. I2C Interfaces

SC650T provides five I2C interfaces. As an open drain output, each I2C interface should be pulled up to
1.8V voltage. The SENSOR_I2C interface supports only sensors of the aDSP architecture.
CAM/DCAM_I2C bus is controlled by Linux Kernel code and supports connection to video output related
devices.
