Note: *
Set the clock source in SCR. Clear the RIE,
TIE, TEIE, MPIE, TE, and RE bits to 0.*
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 one 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.
In simultaneous transmitting and receiving,
the TE and RE bits should be cleared to 0 or
set to 1 simultaneously.
