8.4.1 Device Configuration in GPIO Mode

The TUSB564 is in GPIO configuration when I2C_EN = “0”. The TUSB564 supports the following configurations: USB 3.1 only, 2 DisplayPort lanes + USB 3.1, or 4 DisplayPort lanes (no USB 3.1). The CTL1 pin controls whether DisplayPort is enabled. The combination of CTL1 and CTL0 selects between USB 3.1 only, 2 lanes of DisplayPort, or 4-lanes of DisplayPort as detailed in Table 8-2. The AUXp or AUXn to SBU1 or SBU2 mapping is controlled based on Table 8-3.

After power-up (VCC from 0 V to 3.3 V), the TUSB564 defaults to USB3.1 mode. The USB PD controller upon detecting no device attached to Type-C port or USB3.1 operation not required by attached device must take TUSB564 out of USB3.1 mode by transitioning the CTL0 pin from L to H and back to L.
