15.4.4
Before transmitting and receiving data, you should first clear the TE and RE bits in SCR to 0, then
initialize the SCI as shown in figure 15.5. Do not write to SMR, SCMR, IrCR, or SEMR while the
SCI is operating. This also applies to writing the same data as the current register contents. When
the operating mode, transfer format, etc., is changed, the TE and RE bits must be cleared to 0
before making the change. When the TE bit is cleared to 0, the TDRE flag is set to 1. Note that
clearing the RE bit to 0 does not initialize the contents of the RDRF, PER, FER, and ORER flags,
or the contents of RDR. When the external clock is used in asynchronous mode, the clock must be
supplied even during initialization.
