Transmitting Multiprocessor Serial Data: Figure 12.9 shows a sample flowchart for
transmitting multiprocessor serial data. The procedure is as follows (the steps correspond to the
numbers in the flowchart):
1. SCI status check and transmit data write: Read the serial status register (SSR), check that the
2. Continue transmitting serial data: Read the TDRE bit to check whether it is safe to write (if it
