• Manufacturer Part Number: HD6433935
• Description: 8-Bit MICROCONTROLLER
• Manufacturer: Hitachi

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 10.3.3, 2. Operation in
Asynchronous Mode.
Figure 10-19 shows an example of a flowchart for multiprocessor data transmission. This
procedure should be followed for multiprocessor data transmission after initializing SCI3.
