character units, so a 16 pulse synchronization clock is output. To receive in 1-character units,
select an external clock source.
Transmitting and Receiving Data: SCI Initialization (synchronous mode). Before transmitting,
receiving, or changing the mode or communication format, the software must clear the TE and RE
bits to 0 in the serial control register (SCSCR), then initialize the SCI. Clearing TE to 0 sets TDRE
to 1 and initializes the transmit shift register (SCTSR). Clearing RE to 0, however, does not
initialize the RDRF, PER, FER, and ORER flags and receive data register (SCRDR), which retain
their previous contents.
Figure 13.15 is a sample flowchart for initializing the SCI. The procedure for initializing the SCI
is:
1. Select the clock source in the serial control register (SCSCR). Leave RIE, TIE, TEIE, MPIE,
2. Select the communication format in the serial mode register (SCSMR).
3. Write the value corresponding to the bit rate in the bit rate register (SCBRR) unless an external

serial control register (SCSCR) to 1. Also set RIE, TIE, TEIE and MPIE. Setting TE and RE
allows use of the TxD and RxD pins.
