Figure 15.13 shows a sample flowchart for transmitting serial data.
Use the following procedure for serial data transmission after enabling the SCIF for
transmission.
Write transmit data to SCFTDR,
read TDFE and TEND flags
and then clear the flags to 0
Read TEND flag in SCFSR
Clear TE bit in SCSCR to 0
Read TDFE flag in SCFSR
