Initialization
Before transmitting and receiving data, initialize the SCI as described below. Initialization is also
necessary when switching from transmit mode to receive mode, or vice versa.
[1] Clear the TE and RE bits in SCR to 0.
[2] Clear the error flags ERS, PER, and ORER in SSR to 0.
[3] Set the O/E bit and CKS1 and CKS0 bits in SMR. Clear the C/A, CHR, and MP bits to 0, and
[4] Set the SMIF, SDIR, and SINV bits in SCMR.
[5] Set the value corresponding to the bit rate in BRR.
[6] Set the CKE0 bit in SCR. Clear the TIE, RIE, TE, RE, MPIE, TEIE and CKE1 bits to 0.
[7] Wait at least one bit interval, then set the TIE, RIE, TE, and RE bits in SCR. Do not set the TE

set the STOP and PE bits to 1.
When the SMIF bit is set to 1, the TxD and RxD pins are both switched from ports to SCI pins,
and are placed in the high-impedance state.
If the CKE0 bit is set to 1, the clock is output from the SCK pin.
bit and RE bit at the same time, except for self-diagnosis.
