"The receive buffer must be read before the recently re-
ceived data character on the serial input is shifted into
the receive data FIFO. This FIFO is three bytes deep.
Thus, if the buffer is not read, the fifth character just ar-
rived causes an overrun condition. There is no bit that
can be set or reset to disable the buffering."
