Automatic Hardware Flow Control by RTS/CTS

Figure 19: Auto RTS/CTS

This panel conﬁgures the On-Chip RTS/CTS Hardware Flow Control provided by the UART. The

function of this panel is similar to the software Flow control panel. However, the stop and start

signals are provided by the RTS and CTS signals. RTS controls the input (receive) direction, while

CTS controls output.

Basics of hardware ﬂow control: When CTS is asserted by the other side, transmission is allowed.

If deasserted, transmission is halted. When the system is ready to receive data, it asserts the RTS

line to the other side. If it needs a pause, it deasserts RTS.

RTS Enable Selects the On-Chip receive Flow control.

RTS on Function is similar to the Xon slider from above.

RTS oﬀ Function is similar to the Xoﬀ slider from above.

CTS Enable Selects the On-Chip transmit Flow control, similar to the Transmit Control above.
