Select the clock source in SCR. Clear the RIE, TIE, TEIE,
MPIE, TE, and RE bits to 0. If clock output is selected in
asynchronous mode, clock output starts immediately after
the setting is made in SCR.
Select the communication format in SMR.
Write the value corresponding to the bit rate in BRR.
This step is not necessary when an external clock is used.
Wait for at least the interval required to transmit or receive
1 bit, then set the TE or RE bit to 1 in SCR. Set the RIE,
TIE, TEIE, and MPIE bits as necessary. Setting the TE
or RE bit enables the SCI to use the TxD or RxD pin.
