5.9. I2C Controller
The hard processor system (HPS) provides five I2C controllers to enable system software to communicate serially with I2C buses. Each I2C controller can operate in master or slave mode and support standard mode of up to 100 Kbps or fast mode of up to 400 Kbps. These I2C controllers are instances of the Synopsys™ DesignWare™ APB I2C (DW_apb_i2c) controller.
Each I2C controller must be programmed to operate in either master or slave mode only. Operating as a master and slave simultaneously is not supported.
