Multiprocessor Serial Data Transmission

Figure 13.16 shows a sample flowchart for multiprocessor serial data transmission. For an ID

transmission cycle, set the MPBT bit in SSR to 1 before transmission. For a data transmission

cycle, clear the MPBT bit in SSR to 0 before transmission. All other SCI3 operations are the same

as those in asynchronous mode.
