Section 2 Connection Procedures  
2.1  
Connecting User System Interface Cable to Emulator Station  
WARNING  
Observe the precautions listed below. Failure to do so  
will result in a FIRE HAZARD and will damage the user  
system and the emulator product or will result in  
PERSONAL INJURY. The USER PROGRAM will be  
LOST.  
1. Always switch OFF the user system and the emulator  
product before the USER SYSTEM INTERFACE CABLE  
is connected to or removed from any part. Before  
connecting, make sure that pin 1 on both sides are  
correctly aligned.  
2. The user system interface cable dedicated to the  
emulator must be used.  
To connect the cable body to the emulator station, follow the instructions below.  
1. Make sure the user system and emulator station are turned off.  
2. After making sure the direction of the cable body connector is correct, firmly insert the cable  
body connector into the emulator station socket (figure 2).

2.2  
Connecting User System Interface Cable to User System  
WARNING  
Always switch OFF the user system and the emulator  
product before the USER SYSTEM INTERFACE CABLE  
is connected to or removed from any part. Before  
connecting, make sure that pin 1 on both sides are correctly  
aligned. Failure to do so will result in a FIRE HAZARD and  
will damage the user system and the emulator product or  
will result in PERSONAL INJURY. The USER PROGRAM will  
be LOST.  
To connect the cable head to the user system, follow the instructions below.  
2.2.1 Installing IC Socket  
After checking the location of pin 1 on the IC socket, apply epoxy resin adhesive to the bottom of  
the IC socket for an FP-64A package, and fasten it to the user system before soldering.  
4
 
 
2.2.2  
Soldering IC Socket  
After fastening, solder the IC socket for an FP-64A package to the user system. Be sure to  
completely solder the leads so that the solder slops gently over the leads and forms solder fillets.  
(Use slightly more solder than the MCU.)  
2.2.3  
Inserting Cable Head  
CAUTION  
Check the location of pin 1 before inserting.  
Align pin 1 on the IC socket for an FP-64A package on the user system with pin 1 on the user  
system interface cable head, and insert the user system interface cable head into the IC socket on  
the user system, as shown in figure 3.  
2.2.4  
Fastening Cable Head  
CAUTION  
1. Use a Phillips-type screwdriver whose head matches  
the screw head.  
2. The tightening torque must be 0.0784 N•m or less.  
If the applied torque cannot be accurately measured,  
stop tightening when the force required to turn the screw  
becomes significantly greater than that needed when first  
tightening. If a screw is tightened too much, the screw  
head may break or an IC socket contact error may be  
caused by a crack in the IC socket solder.  
3. If the emulator does not operate correctly, cracks might  
have occurred in the solder. Check conduction with  
a tester and re-solder the IC socket if necessary.  
Fasten the user system interface cable head to the IC socket for an FP-64A package on the user  
system with the four screws (M2.0 x 12 mm) provided. Each screw should be tightened a little at  
a time, alternating between screws on opposing corners. Take special care, such as manually  
securing the IC socket soldered area, to prevent the soldered IC socket from being damaged by  
overtightening the screws or twisting the components.

Section 3 Installing the MCU to the User System  
CAUTION  
1. Check the location of pin 1 before inserting.  
2. Use a Phillips-type screwdriver whose head matches  
the screw head.  
3. The tightening torque must be 0.0784 N•m or less.  
If the applied torque cannot be accurately measured,  
stop tightening when the force required to turn the screw  
becomes significantly greater than that needed when first  
tightening. If a screw is tightened too much, the screw  
head may break or an IC socket contact error may be  
caused by a crack in the IC socket solder.  
4. If the MCU does not operate correctly, cracks might have  
occurred in the solder. Check conduction with a tester  
and re-solder the IC socket if necessary.  
Check the location of pin 1 before inserting the MCU into the IC socket on the user system, as  
shown in figure 8. After inserting the MCU, fasten the socket cover with the provided four  
screws (M2.0 x 8 mm). Take special care, such as manually securing the IC socket soldered area,  
to prevent the IC socket from being damaged by overtightening the screws or twisting the  
components.

Section 4 Verifying Operation  
1. When using the H8/300 series E6000 emulator (HS3008EPI60H), turn on the emulator  
according to the procedures described in the H8/300 Series E6000 Emulator User's Manual  
(HS3008EPI60HE).  
2. Verify the user system interface cable connections by accessing the external memory and ports  
to check the bus states of the pins. If an error is detected, recheck the soldered IC socket and  
the location of pin 1.  
3. The emulator connected to this user system interface cable supports two kinds of clock  
sources: an emulator internal clock and an external clock on the user system. For details, refer  
to the H8/300 Series E6000 Emulator User's Manual (HS3008EPI60HE).  
To use the emulator internal clock  
Select the clock in the emulator station as the system clock (φ), by using the CLOCK  
command (emulator command).  
To use the external clock on the user system as the system clock  
Select target clock t or t with the CLOCK command (emulator command). Supply the  
external clock from the user system to the emulator. Connect a crystal oscillator to the  
EXTAL and XTAL terminals for the system clock. The system clock (φ) has the same  
frequency as the external clock.  
Figure 9 shows the oscillator circuit on the user system interface cable.

Section 5 Notice  
1. Make sure that pin 1 on the user system IC socket is correctly aligned with pin 1 on the cable  
head before inserting the cable head into the user system IC socket.  
2. The dimensions of the recommended mount pad for the user system IC socket are different  
from those of the MCU.  
3. This user system interface cable is specifically designed for the HS3008EPI60H emulator. Do  
not use this cable with any other emulator station.  
4. To prevent breaking of wires in the cable body, do not place heavy or sharp metal objects on  
the user system interface cable.  
5. While the emulator station is connected to the user system with the user system interface  
cable, force must not be applied to the cable head. Place the emulator station, user system  
interface cable, and user system as shown in the example in figure 10.
