Baud Rate Generator
0839I–AVR–06/02
• Bit 1 – RXB8: Receive Data Bit 8
When CHR9 is set (one), RXB8 is the ninth data bit of the received character.
• Bit 0 – TXB8: Transmit Data Bit 8
When CHR9 is set (one), TXB8 is the ninth data bit in the character to be transmitted.
The baud rate generator is a frequency divider that generates baud rates according to
the following equation:
•
•
•
For standard crystal frequencies, the most commonly used baud rates can be generated
by using the UBRR settings in Table 15. UBRR values that yield an actual baud rate dif-
fering less than 2% from the target baud rate, are boldfaced in the table. However, using
baud rates that have more than 1% error is not recommended. High error ratings give
less noise resistance.
