Figure 15.12 shows a sample flowchart for initializing the SCIF.
PFC setting for external pins used
Set RTRG[1:0] and TTRG[1:0] bits
Set TE and RE bits in SCSCR
Set TFRST and RFRST bits
in SCFCR, and clear TFRST

Leave the TE and RE bits cleared
to 0 until the initialization almost
ends. Be sure to clear the TIE,
RIE, TE, and RE bits to 0.
Set the data transfer format in
SCSMR.
Set CKE[1:0].
Write a value corresponding to
the bit rate into SCBRR. This
is not necessary if an external
clock is used.
Sets PFC for external pins used.
Set as RxD input at receiving and
TxD at transmission.
Set the TE or RE bit in SCSCR
to 1. Also set the TIE, RIE, and
REIE bits to enable the TxD,
RxD, and SCK pins to be used.
When transmitting, the TxD pin
will go to the mark state.
When receiving in clocked
synchronous mode with the
synchronization clock output (clock
master) selected, a clock starts to
be output from the SCK pin at this
point.
