21. Serial Communication Interface with FIFO (SCIF)
5. When modem control is enabled, the SCIF_RTS signal is output when SCFRDR is empty.
Figure 21.14 shows an example of the operation when modem control is used.

When SCIF_RTS is 0, reception is possible. When SCIF_RTS is 1, this indicates that
SCFRDR contains bytes of data equal to or more than the SCIF_RTS output active trigger
count. The SCIF_RTS output active trigger value is specified by bits 10 to 8 in SCFCR. For
details, see section 21.3.9, FIFO Control Register n (SCFCR). In addition, SCIF_RTS is also 1
when the RE bit in SCSCR is cleared to 0.
