Figure 10-16 Example of Inter-Processor Communication Using Multiprocessor Format
(Sending data H'AA to receiver A)
There is a choice of four data transfer formats. If a multiprocessor format is specified, the parity bit
specification is invalid. See table 10-11 for details.
For details on the clock used in multiprocessor communication, see 10.1.4, Operation in
Synchronous Mode.

Multiprocessor transmitting
Figure 10-17 shows an example of a flowchart for multiprocessor data transmission. This procedure
should be followed for multiprocessor data transmission after initializing SCI3.
