1. Select the clock source in SCR. Clear the RIE, TIE,
2. Select the communication format in SMR.
3. Write the value corresponding to the bit rate in BRR.
4. Wait for at least the interval required to transmit or
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.
This step is not necessary when an external clock is
used.
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.
