254 / 433 page  254 TPR0327AY–SMS–30Jan09 AT90SCR100 18.12 Examples of Baud Rate Setting For AT90SCR100 frequencies, the most commonly used baud rates for asynchronous operation can be generated by using the UBRR settings in Table 18-9 and Table 18-10. UBRR values which yield an actual baud rate differing less than 0.5% 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 “Asynchronous Operational Range” on page 246). The error values are calculated using the following equation: Note: 1. UBRR = 0, Error = 0.0% Error[%] BaudRateClosest Match BaudRate -------------------------------------------------------- 1 – ⎝⎠ ⎛⎞ 100% • = Table 18-9.
