Serial Data Transmission (Asynchronous Mode):
Figure 17.8 shows a sample flow chart for serial data transmission. After enabling the SCI
transmission, transmit serial data following the procedure shown below:
SCTDR and clear TDRE bit in
Read TDRE bit in SCSSR
Write transmission data to
Read TEND bit in SCSSR
Set SCPDR and SCPCR
Clear TE bit SCSCR to 0
All data transmitted?
Start transmission
End transmission
Break output?
SCSSR to 0
TDRE = 1?
TEND = 1?

Section 17 Serial Communication Interface (SCI)
(1) SCI status check and transmit data
(2) To continue transmitting serial data:
(3) To output a break at the end of serial
write:
Read the serial status register
(SCSSR), check that the TDRE bit is 1,
then write transmit data in the transmit
data register (SCTDR) and clear TDRE
to 0.
Read the TDRE bit to check whether it
is safe to write (if it reads 1); if so, write
data in SCTDR, then clear TDRE to 0.
transmission:
Set the SC port data register (SCPDR)
and SC port control register (SCPCR),
then clear the TE bit to 0 in the serial
control register (SCSCR). For SCPCR
and SCPDR settings, see section
17.2.8, Port SC Control Register
(SCPCR)/Port SC Data Register
(SCPDR).
