This UART (Universal Asynchronous Receiver Transmitter) is designed to make an
interface between a RS232 line and a wishbone bus, or a microcontroller, or an IP core.
It works fine connected to the serial port of a PC for data exchange with custom
electronic.
It was built in the perspective to be very small, but efficient. It had to fit in a small FPGA.
It is not suited to interface a modem as there is no control handshaking (CTS/RTS).
It integrate two separate clocks, one for wishbone bus, the other for bitstream generation.
This has the advantage to let the user bring his own desired frequency for the baudrate.
