- *  Should we use a polled or interrupt drived console?

- *  NOTE: This is defined in the custom/leon.cfg file.

- *  WARNING:  In sis 1.6, it did not appear that the UART interrupts
- *            worked in a desirable fashion.  Immediately upon writing
- *            a character into the TX buffer, an interrupt was generated.
- *            This did not allow enough time for the program to put more
- *            characters in the buffer.  So every character resulted in
- *            "priming" the transmitter.   This effectively results in
- *            in a polled console with a useless interrupt per character
- *            on output.  It is reasonable to assume that input does not
- *            share this problem although it was not investigated.
