8.3.13.3 I2C Address Setting

A HUB, MCU, or automotive processor host can use I2C_SCL2 or I2C_SDA2 for loading firmware patches or general status communication. Once the boot process is complete, each I2C port is assigned a unique target address as determined by the TVSP pin. The target address used by each port on the I2C2s bus are determined from the application configuration.
