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