arrangement (to provide a 3-byte delay) in addition to the 8-bit receive shift
register. This arrangement creates additional time for the CPU to service an
interrupt at the beginning of a block of high-speed data. The receive error
FIFO stores parity and framing errors and other types of status information
for each of the three bytes in the receive data FIFO.
Incoming data is routed through one of several paths depending on the
mode and character length. In the Asynchronous mode, serial data is
