This divide factor d

means, changing f
values. For the baudrates to be detected, the following relations are always valid :
A requirement for detecting standard baudrates up to 230.400 kBaud is the f
value of 11.0592 MHz. With the value FD_VALUE in register FDV the fractional divider

Note: If the deviation of the baudrate after autobaud detection is to high, the baudrate
Non-Standard Baudrates
Due to the relationship between Br0 to Br8 in Table 63 concerning the divide factor d
other baudrates than the standard baudrates can be also selected. E.g. if a baudrate of
50 kBaud has to be detected, Br2 is e.g. defined as baudrate for the 50 kBaud setection.

required to get a more precise baudrate with less error.
