7.4.2 Device Configuration In I2C Mode

The TUSB1046-DCI is in I2C mode when I2C_EN is not equal to “0”. The same configurations defined in GPIO mode are also available in I2C mode. The TUSB1046-DCI USB3.1 and DisplayPort configuration is controlled based on Table 7-5. The AUXp or AUXn to SBU1 or SBU2 mapping control is based on Table 7-6.
