Clear To Send input pin (CTS) is 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. The CTS to DE assertion delay (T1) assumes the UART Transmit Data Register
has been loaded with data prior to CTS assertion.
