Table 2 shows the UART baudrates supported.
3.1.1.2 Detailed UART Behavior
After reset the UART interface is configured with one start bit, eight data bits, no parity
bit and one stop bit. The least significant bit is transmitted first.
The polarity of the UART signals can be changed with the BD_DATA parameter
UART_Invert. The default (non-inverted) behavior is shown in Table 3
