The individual serial ports are capable of operating at baud rates in excess of 500,000 bps
in the asynchronous mode, and 8 times faster than that in the synchronous mode. Either 7
or 8 data bits may be transmitted and received in the asynchronous mode. The so-called
"9th" bit or address bit mode of operation is also supported. The “9th” bit can be set high
or low by accessing the appropriate serial port register. Although Parity and multiple stop
bits are not directly supported by the hardware, the “9th” bit can be used to issue an extra
stop bit (9th-bit high) or toggled to indicate parity.
