8.4.3 Port Configuration

The TUSB8043A port configurations can be selected by registers or efuse. The Port Used Configuration register (USED[3:0]) define how many ports can possibly be reported by the hub. The device removable configuration register (RMBL[3:0]) define if the ports that USB 3.2 are reported as used have permanently connected devices or not. The USB 2.0 Only Port register (USB2_ONLY[3:0]) define whether or not a used port is reported as part of the USB 2.0 hub or both the USB2.0 and SS hubs. The USB2_ONLY field enables the USB2.0 port even if the corresponding USED bit is low. The internal HID port will always be the highest number USB2.0 port. Table 5 shows examples of the possible combinations.
