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.  
CAUTION  
When connecting or removing the user system interface  
cable, apply force only in the direction suitable for  
connection or removal, while making sure not to bend or  
twist the cable or connectors. Otherwise, the connectors will  
be damaged.  
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).

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 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 a TFP-120 package, and fasten it to the user system before soldering.

2.2.2  
Soldering IC Socket  
After fastening, solder the IC socket for a TFP-120 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 a TFP-120 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 0.098 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 a TFP-120 package on the user  
system with the four screws (M2 x 12 mm; with four flat washers) 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 0.098 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 x 8 mm; with four flat washers). 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 E6000 emulator for the H8S/2655 series, turn on the emulator according to the  
procedures described in the H8S Series E6000 Emulator User's Manual (HS2000EPI61HE).  
2. Verify the user system interface cable connections by accessing the external memory and ports  
to check the bus states of the pins with the MEMORY_FILL command (emulator command). 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  
as the MCU clock: an emulator internal clock and an external clock on the user system. For  
details, refer to the H8S/2655 series E6000 Emulator Supplementary Information  
(HS2655EPI61HE).  
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  
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 user system interface cable  
has the oscillator circuits shown in figure 9. For details, refer to section 20, Clock Pulse  
Generator, in the H8S/2655 Series Hardware Manual.

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 HS2655EPI61H 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.
