Section 13 Serial Communication Interface (SCI)
13.5.2
Figure 13.16 shows a sample flowchart for multiprocessor serial data reception. If the MPIE bit in
SCR 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 in asynchronous mode. Figure
13.15 shows an example of SCI operation for multiprocessor format reception.
