For standard crystal, resonator and external oscillator frequencies, the most commonly used
baud rates for asynchronous operation can be generated by using the UBRR settings in
18-9
from the target baud rate, are bold in the table. Higher error ratings are acceptable, but the
Receiver will have less noise resistance when the error ratings are high, especially for large
serial frames (see
