Section 12 Serial Communication Interface
Set the clock source in SCR. Clear the
RIE, TIE, TEIE, MPIE, TE, and RE bits to
0. *
Set 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.
