There is a choice of four data transfer formats. If a multiprocessor format is specified, the parity
bit specification is invalid. See table 10.14 for details.
For details on the clock used in multiprocessor communication, see section 10.3.3, 2. Operation in
Asynchronous Mode.
Figure 10.22 shows an example of a flowchart for multiprocessor data transmission. This
procedure should be followed for multiprocessor data transmission after initializing SCI3.
