Multiprocessor Serial Data Reception
Figure 14-17 shows a sample flowchart for multiprocessor serial data reception. If the MPIE bit in
SCR3 is set to 1, data is skipped until data with a 1 multiprocessor bit is sent. On receiving data
with a 1 multiprocessor bit, the receive data is transferred to RDR. An RXI interrupt request is
generated at this time. All other SCI operations are the same as those in asynchronous mode.
Figure 14-18 shows an example of SCI operation for multiprocessor format reception.
