Data Rate Multiplier

Clock Mode	Max bps		Description
		Auto clock mode enables
		applications to request any baud
Auto	921,600	rate up to 921,600. The hardware
		drivers will select the correct clock
		multiplier based on the baud rate
		requested
		The X1 clock mode mimics a
		standard COM port. The hardware
X1	115,200	drivers lock the clock to the
		standard rate. The port will run at
		the baud rate requested by the
		application.
		The X2 clock mode locks the ports
		hardware clock at double the
		standard rate. The baud rate the
		port runs at will always be double
X2	230,400	the rate requested by the
		applications. This mode is useful
		for legacy applicattions which
		cannot request baud rates over
		115,200
		The X4 clock mode locks the ports
		hardware clock at four times the
		standard rate. The baud rate the
X4	460,800	port runs at will always be four
		times the rate requested by the
		application. This mode is useful for
		legacy applications which cannot
		request baud rates over 115.200.
		The X8 clock mode locks the ports
		hardware clock at eight times the
		standard rate. The baud rate the
X8	921,600	port runs at will always be eight
		times the rate requested by the
		application. This mode is useful for
		legacy applications which cannot
		request	baud rates over 115.200.
