GOWIN USB1.1
Universal Serial Bus, commonly known as USB, standardizes the connection and communication between computers and external devices.
Gowin USB1.1 IP is based on USB1.1 protocol and USB Device Class only supports Communications Device Class (CDC) at present.
One end of the Gowin USB1.1 IP is the USB interface (I/O position is fixed, and you can see Package for details) and the other end is data of other format.
If UART is enabled, the communication between USB and UART can be realized. Otherwise, the other end is 8bit data in parallel and it communicates by handshake signal. IP supports the configuration of the receive and transmit buffers size.
