921,600
select the correct clock multiplier based on the baud
rate requested
The X1 clock mode mimics a standard COM port. The
hardware drivers lock the clock to the standard rate.
115,200
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 the rate requested by the
230,400
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 port
runs at will always be four times the rate requested by
460,800
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 port
runs at will always be eight times the rate requested by
921,600
