3.14. I2C Interfaces

SA800U-WF provides six groups of I2C interfaces. As an open drain output, each I2C interface should be
pulled up to 1.8 V. CCI_I2C bus is controlled by Linux Kernel code and supports connection to video
output related devices. SSC_I2C only supports connection to
low-power and always-on use cases.
