Figure 10.19 Example of Interprocessor Communication Using Multiprocessor Format
(Data H'AA Sent to Receiving Processor A)
Four communication formats are available. Parity-bit settings are ignored when a multiprocessor
format is selected. For details see table 10.14.
For a description of the clock used in multiprocessor communication, see 10.3.4, Operation in
Asynchronous Mode.
