9.3.4.7 USB2.0 Low-Speed Endpoint
The USB low-speed Endpoint is a USB 2.0 low-speed (1.5 Mbps) interface used to support HID class based accesses. The TPS65982 supports control of endpoint EP0. This endpoint enumerates to a USB 2.0 bus to provide USB-Billboard information to a host system as defined in the USB Type-C standard. EP0 is used for advertising the Billboard Class. When a host is connected to a device that provides Alternate Modes which cannot be supported by the host, the Billboard class allows a means for the host to report back to the user without any silent failures.
Figure 9-38 shows the USB Endpoint physical layer. The physical layer consists of the analog transceiver, the Serial Interface Engine, and the Endpoint FIFOs and supports low speed operation.
Figure 9-38 USB Endpoint PhyThe transceiver is made up of a fully differential output driver, a differential to single-ended receive buffer and two single-ended receive buffers on the D+/D– independently. The output driver drives the D+/D– of the selected output of the Port Multiplexer. The signals pass through the 2nd Stage Port Data Multiplexer to the port pins. When driving, the signal is driven through a source resistance RS_EP. RS_EP is shown as a single resistor in USB Endpoint Phy but this resistance also includes the resistance of the 2nd Stage Port Data Multiplexer defined in Port Data Multiplexer Requirements and Characteristics. RPU_EP is disconnected during transmit mode of the transceiver.
When the endpoint is in receive mode, the resistance RPU_EP is connected to the D– pin of the top or bottom port (C_USB_TN or C_USB_BN) depending on the detected orientation of the cable. The RPU_EP resistance advertises low speed mode only.
