4. When modem control is enabled, transmission can be stopped and restarted in accordance with
the CTS2 input value. When CTS2 is set to 1, if transmission is in progress, the line goes to
the mark state after transmission of one frame. When CTS2 is set to 0, the next transmit data
is output starting from the start bit.
Figure 19.7 shows an example of the operation when modem control is used.
