4. When modem control is enabled, transmission can be stopped and restarted in accordance with
the
SCIF0_CTS
input value. When
SCIF0_CTS
is set to 1 during transmission , the line goes
to the mark state after transmission of one frame. When
SCIF0_CTS
is set to 0, the next
transmit data is output starting from the start bit.
Figure 21.11 shows an example of the operation when modem control is used.
