Figure 19.5 shows a sample serial transmission flowchart. After SCIF transmission is enabled, use
the following procedure to perform serial data transmission.

Read serial status register 2 (SCSSR2) and
check that the TDFE flag is set to 1, then
write transmit data to the transmit FIFO
data register 2 (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 port SC data register (SCPDR) and port
SC control register (SCPCR), then clear the
TE bit to 0 in the serial control register 2
(SCSCR2). For information on SCPDR2
and SCPCR2, see section 17.2.8.
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 SCFTDR indicated by the upper 8
bits of the FIFO data count set register 2
(SCFDR2).
