For standard crystal frequencies, the most commonly used baud rates can be generated by using the UBR settings in
Table 19. UBR values which yield an actual baud rate differing less than 2% from the target baud rate, are bold in the table.
However, using baud rates that have more than 1% error is not recommended. High error ratings give less noise
resistanse.
