1.20 Emulator MCU
1.20 Emulator MCU
The M37471RSS and the M37478RSS are emulator MCUs for the 7470/7471/7477/7478 group software
development. When an emulator is connected to the socket on the top surface, user program debugging
can be performed efficiently by using a real-time trace function, etc.
It is possible to monitor every internal bus information through the emulator because 16 address bus
signals, two-way data bus signals and SYNC, RD, WR and
f signals are output from the socket on the top
surface.
In the debug system using the M37471RSS and the M37478RSS, the MCU pins for emulator are directly
connected to the user system. This permits debugging in a condition similar to a real mounting condition.
For details of development support systems for the M37471RSS and the M37478RSS, refer to the
“DEVELOPMENT SUPPORT TOOLS FOR MICROCOMPUTER” data book.
Figure 1.20.1 shows a pin connection diagram of
the M37471RSS and M37478RSS.
