CHAPTER 1 GENERAL
The IE-784000-R In-Circuit Emulator is a development tool that efficiently debugs the hardware and software of
an application system using NEC’s 78K/IV series microcomputer.
This in-circuit emulator is used in combination with the optional emulation board (IE-784000-R-EM), I/O emulation
board (IE-784026-R-EM1, etc.), and emulation probe (EP-78230GC-R, etc.).
The in-circuit emulator is connected to a host machine with an optional interface board (IE-70000-98-IF-B, IE-
70000-98N-IF, IE-70000-PC-IF-B, or IE-78000-R-SV3).

CHAPTER 1 GENERAL

1.1 Features
Here are the features of the IE-784000-R:
•High-speed PC bus interface can be used.
•Network interface by Ethernet can be used (an optional network board is necessary).
•Real-time execution, real-time trace
•A wealth of event detection functions and real-time trace functions
•The contents of the real-time tracer can be checked without stopping execution of the emulation CPU.
•The contents of the real-time tracer can be searched.
•Data can be written to the real-time tracer or the user program can be executed in synchronization with events.
•Execution time and the number of time measurements can be measured at three locations.
•The specified data of the internal RAM can be displayed while the emulation CPU operates real-time.
•The execution area of the program area and data access area can be displayed.
•8-bit trace by using an external sense clip.
•1M-byte emulation memory.
•All packages can be supported by using optional I/O emulation board and emulation probe.

1.4 Setup Sequence
The setup sequence is as follows:
<1> Connect the emulation board (IE-784000-R-EM).
→Refer to the User’s Manual for the I/O emulation board.
<2> Connect the I/O emulation board (to emulate the target device).
→Refer to the User’s Manual for the I/O emulation board.
<3> Set the user clock (when necessary).
Change the operating clock on the I/O emulation board when necessary.
→Refer to the User’s Manual for the I/O emulation board.
<4> Connect the I/O emulation board and connector board.
Connectthe connector board (supplied withthe optional emulation probe) tothe I/O emulation board (optional).
→Refer to the User’s Manual for the I/O emulation board or emulation probe.
<5> Connect the accessory cables.
Connect the power cable and interface cable.
→Refer to CHAPTER 2 NAMES AND FUNCTIONS OF RESPECTIVE PARTS in this manual.
<6> Connect the IE-784000-R to peripheral equipment.
Connect the host machine.
→Refer to CHAPTER 6 CONNECTING PERIPHERAL EQUIPMENT in this manual.
<7> Connect the target system.
Connect the emulation probe (optional) and target system.
→Refer to CHAPTER 7 CONNECTING TARGET SYSTEM in this manual and the User’s Manual for the I/O
emulation board or emulation probe.

1.5 Target Device
The IE-784000-R can emulate the devices in the 78K/IV series when used in combination with the optional
emulationboard, optional I/O emulation board, and optionalemulation probe. For details, refer to the User’sManuals
for the respective emulation boards.
1.6 Emulation Board and I/O Emulation Board
The emulation board and I/O emulation board are optional.
If the target device is a 78K/IV series product, use the IE-784000-R-EM as the emulation board.
For the details of the I/O emulation board, refer to the User’s Manual for the I/O emulation board.
1.7 Emulation Probe
The emulation probe is optional.
