ZipCPU comes to the rescue once again with a UART implementation with a Wishbone interface. The BoxLambda variant of the wbuart core contains some modifications for enabling and clearing of specific interrupt events. These modifications are documented in a separate section of the core's spec.

The wbuart core is instantiated without hardware flow control.
