the Clear To Send input signal (CTS) is not used for flow control. In this example, it is
assumed that the Driver Enable polarity has been configured to be Active Low and is
represented here by DE. DE asserts after the UART Transmit Data Register has been
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.
