Figure 28.6 shows a sample SCIF initialization flowchart.
Start of initialization
Clear TE and RE bits in
SCSCR to 0
Set TFCL and RFCL
bits in SCFCR to 1
Set CKE1 and CKE0 bits
in SCSCR (leaving TE, RE, TIE,
and RIE bits cleared to 0)
Set data transfer format
in SCSMR
Set value in SCBRR
1-bit interval elapsed?
Set RTRG1-0, TTRG1-0 bits,
and MCE in SCFCR, and clear
TFCL and RFCL bits to 0
Set TE and RE bits in
SCSCR to 1, and set TIE, RIE,
and REIE bits
End of initialization
Wait
No
Yes
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.)
Wait at least one bit interval, then 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 SCIF_TXD and
SCIF_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.

Read flags of ER, DR,
and BRK in SCFSR and ORER
in SCLSR, then clear them to 0
