By using the EP-753304DU-R in such connections, a debugging environment for the µPD753304 is created, making comprehensive debugging of the target system hardware and software possible. See CHAPTER 2 CONNECTIONS for concerning concrete connection methods. Figure 1-1.

(1) Emulation probe The emulation probe is configured from the following 3 components. • 42-pin shrink DIP probe Connects the IE-75001-R and the target system. • Ground clip Connects to the target system’s GND. The ground clip makes the GND potential of the IE-75001-R and the target system the same, and protects the system against static electricity and noise. • External sense clips Consists of 8 sense clips. These clips are used to monitor the IC pin voltage level of the target system. (2) Adapter board The adapter board is used to connect the emulation probe and the emulation board (IE-75300-R-EM). The adapter board also includes functions to set mask options. For details, see CHAPTER 3 SETTING MASK OPTIONS. 2 CHAPTER 1 GENERAL DESCRIPTION Figure 1-2.

(1) Connecting the IE-75300-R-EM and the adapter board (2) Connecting the IE-75001-R and the emulation probe (3) Connecting the emulation probe and the target system (4) Connecting the external sense clips (if external sense clips are used) (5) Switching on the power Next, the details of each item in the connection procedure are explained. 5 CHAPTER 2 CONNECTIONS (1) Connecting IE-75300-R-EM and adapter board Connect the adapter board to the IE-75300-R-EM. <1> While placing a spacer between the IE-75300-R-EM and the adapter board, connect the connectors CN1 to CN4 of the IE-75300-R-EM and the connectors CN1 to CN4 of the adapter board. <2> Fasten the spacer between the IE-75300-R-EM and the adapter board using the spacer installation screws. <3> Switch off the power of the IE-75001-R. <4> Take off the 6 screws on the top of the IE-75001-R unit, then open the unit’s top cover. <5> Pull the card pullers on both ends of the board forward and pull out the IE-75000-R-BKNote. <6> Screw the IE-75300-R-EM to the IE-75000-R-BK together. <7> Replace the IE-75000-R-BK screwed together with the IE-75300-R-EM to the original position of the IE-75001-R. Note In the case of the IE-75000-R, the IE-75000-R-EM and the IE-75000-R-BK are installed screwed together. Therefore, pull out the IE-75000-R-BK from the main unit in the above sequence <3>→<4>→<5>, remove the screws and pull off the IE-75000-R-EM before following steps <1>→<2>→<6>→<7>. Figure 2-1. Connecting IE-75300-R-EM and Adapter Board Adapter Board CN5 Spacer Installation Screws CN4 IE-75300-R-EM 6 CN1 CHAPTER 2 CONNECTIONS (2) Connecting IE-75001-R and emulation probe <1> Connect the emulation probe to the emulation probe DIN connector (CN5 of the adapter board) on the top of the IE-75001-R. <2> After connection, be sure to fasten the emulation probe to the IE-75001-R with the installation screws provided. Figure 2-2. Connecting IE-75001-R and Emulation Probe Installation Screws Emulation Probe (CN5) IE-75001-R 7 CHAPTER 2 CONNECTIONS (3) Connecting emulation probe and target system Connect the emulation probe to the target system by the following procedure. Cautions 1. Before connecting the emulation probe to the target system, be sure to connect the ground clip first. Otherwise, the IE-75001-R could be damaged by static electricity, etc. 2. When making connections, be careful not to reverse the pins. If connections are incorrect, this could damage the IE-75001-R. <1> <2> <3> <4> Switch off the power of the target system. Solder the shrink DIP socket to the target system. Connect the emulation probe’s ground clip to the ground (GND) pin of the target system. Align the No. 1 pin of the 42-pin shrink DIP at the end of the emulation probe with that of the shrink DIP socket of <2> soldered into the target system, then insert the emulation probe. Figure 2-3. 42-Pin Shrink DIP Emulation Probe Connection Ground Clip 42-Pin Shrink DIP In-Circuit Emulator External Sense Clips 1 42 Shrink DIP Socket 21 22 Target System 8 CHAPTER 2 CONNECTIONS (4) Connecting external sense clip The emulation probe is provided with 8 external sense clips which can trace hardware signals on the target system in real time. Since the external sense clips are directly connected to the input buffer HCT244 inside the in-circuit emulator unit, they have TTL level inputs. The 8 external sense clips are normally input signal lines. However, by setting the OUT command on the in-circuit emulator, the signal line of external sense clip 1 can be used as an external trigger output signal line in the case of an event (see the in-circuit emulator manual for details). Cautions 1. Connect the external sense clip to a TTL level signal line only. Otherwise, it will not detect the high level and low level accurately. Also, depending on the voltage level, the IE-75001-R’s sensor could be damaged. 2. Before using external sense clip 1 as an external trigger output, ensure that external sense clip 1 is not connected to the signal output line, otherwise a fault may result. 9 CHAPTER 2 CONNECTIONS Connect the external sense clip by the following procedure if it is used. <1> <2> <3> <4> Switch off the power of the target system first, then that of the IE-75001-R. Install the IC clip (commercially available) on the IC which is to be traced in the target system. Connect the external sense clip to the IC clip installed. Switch on the power to the IE-75001-R first, then that of the target system. Figure 2-6. Connecting External Sense Clip External Sense Clip IC Clip IC Target System Remark If an external sense clip is connected, be sure to use an IC clip insofar as possible. This helps prevent faulty contact and improves operability. 10 CHAPTER 2 CONNECTIONS 2.2 Power ON and OFF Sequence After the connection of the emulation probe to the target system has been completed, switch on the power. The sequence for switching the power on/off is shown below. Caution Be sure to follow the correct sequence for switching the power ON and OFF. Otherwise, the IE-75001-R could be damaged. (1) If the IE-75001-R is connected to the target system • Power ON sequence <1> Switch on the power of the IE-75001-R. <2> Switch on the power of the target system. • Power OFF sequence <1> Switch off the power of the target system. <2> Switch off the power of the IE-75001-R. 11 CHAPTER 2 CONNECTIONS 2.3 Removing Emulation Probe from Target System Remove the emulation probe from the target system by the following procedure. <1> <2> <3> <4> Switch off the power of the target system. Switch off the power of the IE-75001-R. Lift the shrink DIP socket lever. Pull out vertically the extractor at the end of the emulation probe, and remove the emulation probe from the shrink DIP socket. Figure 2-7. 42-Pin Shrink DIP Emulation Probe Removal Extractor Shrink DIP Socket Lever Target System 12 CHAPTER 3 SETTING MASK OPTIONS CHAPTER 3 SETTING PORT 3 The DP1 switch on the adapter board is for the port 3 setting. When these switches are ON, pull-up resistorsNote 1 (47 kΩ) or pull-down resistorsNote 2 (47 kΩ) are connected. At shipping, the DP1 switches are set in the OFF position. Notes 1. P33 2.
