Section 16 Serial Communication Interface with FIFO (SCIF)
• Transmitting Serial Data (Clocked Synchronous Mode)
Figure 16.11 shows a sample flowchart for transmitting serial data.
Use the following procedure for serial data transmission after enabling the SCIF for transmission.

1 from the TDFE flag to confirm that
writing is possible, them write data to
SCFTDR, and then clear the TDFE
flag to 0.
Read SCFSR and check that the
TDFE flag is set to 1, then write
transmit data to SCFTDR, and read
1 from the TDFE and TEND flags,
then clear these flags to 0.
