Baud Rate Calculation Example
Baud Rate Example (OVER = 0)
Expected Baud
This gives a maximum baud rate of CLK_USART divided by 8, assuming that CLK_USART is
the highest possible clock and that OVER is programmed at 1.
Table 26-2 on page 306
ferent source clock frequencies. This table also shows the actual resulting baud rate and the
error.
The baud rate is calculated with the following formula:
The baud rate error is calculated with the following formula. It is not recommended to work with
an error higher than 5%.
