Transmitting Multiprocessor Serial Data: Figure 15.13 shows a sample flowchart for
transmitting multiprocessor serial data. The procedure for transmitting multiprocessor serial data
is:
1. SCI status check and transmit data write: Read the serial status register (SCSSR), check that
2. To continue transmitting serial data: Read the TDRE bit to check whether it is safe to write (if
3. To output a break at the end of serial transmission: Set the port SC data register (SCPDR) and
