16.6.2
Before transmitting and receiving data, first clear the TE and RE bits in SCR to 0, then initialize
the SCI as described in a sample flowchart in figure 16.15. 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. However, clearing the RE bit to 0 does not
initialize the RDRF, PER, FER, and ORER flags, or RDR.
