Address Output Setting of Separate Bus
When using the separate bus function while debugging using the IE-703089-MC-EM1, switching to the separate
bus output function is not possible by setting the memory address output register (MAM) by software.
Use DIP switch SW5 to output the address of the separate bus function while debugging using the IE-703089-MC-
EM1.
The switches of SW5 and their corresponding ports are shown in Table 2-5.
