Clear To Send input signal (CTS) is not used for flow control. In this example, it is
assumed that the Driver Enable polarity is configured to be Active Low and is represented
here by DE. DE asserts after the UART Transmit Data register is written. DE remains
asserted for multiple characters as long as the Transmit Data register is written with the
next character before the current character has completed.
