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