(2) Baud rate error during transmission
(Target Baud Rate)
UART Baud Rate
The baud rate error of UART (UART0, UART1, UART3) communication during transmission can be calculated
by the following expression. Make sure that the baud rate at the transmission side is within the permissible
baud rate range at the reception side.
Here is an example of setting a UART baud rate at f
(Baud rate error) = (Calculated baud rate value) ÷ (Target baud rate) × 100 − 100 [%]
