12.6.2
Before transmitting and receiving data, you should first clear the TE and RE bits in SCR to 0, then
initialize the SCI as described in a sample flowchart in figure 12.15. When the operating mode,
transfer format, etc., is changed, 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 in SSR is
set to 1. However, clearing the RE bit to 0 does not initialize the RDRF, PER, FER, and ORER
flags in SSR, or RDR.
Note: * In simultaneous transmit and receive operations, the TE and RE bits should both be cleared
