Section 13 Serial Communication Interface (SCI)
13.4.4
Before transmitting and receiving data, you should first clear the TE and RE bits in SCR to 0, then
initialize the SCI as described below. When the operating mode, or transfer format, is changed for
example, the TE and RE bits must be cleared to 0 before making the change using the following
procedure. 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.
