/* USART2 configured as follow:

- BaudRate = 115200 baud

- Word Length = 8 Bits

- One Stop Bit

- No parity

- Hardware flow control disabled (RTS and CTS signals)

- Receive and transmit enabled

- USART Clock disabled

- USART CPOL: Clock is active low

- USART CPHA: Data is captured on the middle

- USART LastBit: The clock pulse of the last data bit is not output to

the SCLK pin
