● Communication procedure
Master/slave mode communication starts as the master CPU transmits address data. The
address data, which is the data chosen when the AD bit is set to "1", determines the slave CPU
that is to be the destination of the communication. A slave CPU uses a program to check
address data, and communicates with the master CPU when the address data matches the
address assigned to that slave CPU.
Figure 14.6-15 is a flow chart showing master/slave mode communication (multiprocessor
mode).
