After reading ER, DR, and BRK flags
Clear TE and RE bits in SCSCR to 0
in SCFSR, and each flag in SCLSR,
Set RTRG[1:0] and TTRG[1:0] bits
Set TE and RE bits in SCSCR to 1,
Set data transfer format in SCSMR
PFC setting for external pins used
in SCSCR (leaving TIE, RIE, TE,
and set TIE, RIE, and REIE bits
in SCFCR, and clear TFRST
Set TFRST and RFRST bits
and RE bits cleared to 0)
Figure 16.3 Sample Flowchart for SCIF Initialization
and RFRST bits to 0
write 0 to clear them

Set the clock selection in SCSCR.
Be sure to clear bits TIE, RIE, TE,
and RE to 0.
Set the data transfer format in
SCSMR.
Write a value corresponding to the
bit rate into SCBRR. (Not
necessary if an external clock is
used.)
Sets PFC for external pins used.
Set as RxD input at reciving and
TxD at transmission.
However, no setting for SCK pin is
required when CKE[1:0] is 00.
Set the TE bit or RE bit in SCSCR
to 1. Also set the RIE, REIE, and
TIE bits. Setting the TE and RE bits
enables the TxD and RxD pins to
be used.
When transmitting, the SCIF will go
to the mark state; when receiving,
it will go to the idle state, waiting for
a start bit.
When the intrnal clock output is
selected, a clock starts to be output
from the SCK pin at this point.
