The transmitter checks UART0_CTS before sending the next data byte. If UART0_CTS is active, the transmitter sends the next byte. To stop the transmitter from sending the following byte, UART0_CTS must be released before the middle of the last STOP bit that is currently being sent (see Figure 7-51). When flow control is enabled, UART0_CTS level changes do not trigger interrupts because the device automatically controls its own transmitter. Without autoflow control, the transmitter sends any data present in the transmitter FIFO and a receiver overrun error may result.
