4.6. I2C Interfaces
The module provides up to five I2C Interfaces. All I2C interfaces are open drain signals and therefore
you must pull them up externally. The reference power domain is 1.8 V. The SENSOR_I2C interface only
supports sensors of the DSP architecture. The CAM_I2C interface supports connection with video output
related devices.
