6.4.2 Device Configuration in I2C Mode

The TUSB1044 is in I2C mode when I2C_EN is equal to “1”. The same configurations defined in GPIO mode are also available in I2C mode. The TUSB1044 USB3.1, DisplayPort, and custom Alternate Mode configuration is controlled based on Table 6-5. The AUXP/N to SBU1/2 mapping control is based on Table 6-5.
