Serial data transmission: Figure 16.6 shows a sample flowchart for serial transmission.
Use the following procedure for serial data transmission after enabling the SCIF for transmission.

1. SCIF status check and transmit data write:
2. Serial transmission continuation procedure:
3. Break output at the end of serial
Read SCSSR2 and check that the TDFE
flag is set to 1, then write transmit data to
the SCFTDR2, read 1 from the TDFE and
TEND flags, then clear these flags to 0.
The number of transmit data bytes that can
be written is 16 - (transmit trigger set
number).
To continue serial transmission, read 1 from
the TDFE flag to confirm that writing is
possible, then write data to SCFTDR2, and
then clear the TDFE flag to 0.
transmission: To output a break in serial
transmission, set the SCPDR and SCPCR,
then clear the TE bit to 0 in the SCSCR2.
For information on SCPDR and SCPCR,
see 16.3.11, SC Port Control Register
(SCPCR), and 16.3.12, SC Port Data
Register (SCPDR).
In steps 1 and 2, it is possible to ascertain
the number of data bytes that can be
written from the number of transmit data
bytes in SCFTDR2 indicated by the upper 8
bits of the SCFDR2.
