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).

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 TFP-80C package, and fasten it to the user system before soldering.  
2.2.2  
Soldering IC Socket  
After fastening, solder the IC socket for an TFP-80C 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.)  
5
 
 
2.2.3  
Inserting Cable Head  
CAUTION  
Check the location of pin 1 before inserting.  
Align pin 1 on the IC socket for an TFP-80C 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 Philips-type screwdriver whose head matches  
the screw head.  
2. The tightening torque must be 0.294 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.  
6
 
 
Fasten the user system interface cable head to the IC socket for an TFP-80C package on the user  
system with the four screws (M2.6 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 Philips-type screwdriver whose head matches  
the screw head.  
3. The tightening torque must be 0.294 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  
(M2.6 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 H8/300L series E6000 emulator (HS3L08EPI60H), turn on the emulator  
according to the procedures described in the H8/300L Series E6000 Emulator User's Manual  
(HS3008EPI60HE).  
2. Verify the user system interface cable connections by accessing ports and checking 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 the MCU clock and  
subclock. For details, refer to the H8/300L 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) and the subclock  
(φw), by using the CLOCK command (emulator command).  
To use the external clock on the user system as the system clock  
Select target clock t2 with the CLOCK command (emulator command). Supply the external  
clock from the user system to the emulator by inputting the external clock from the OSC1  
terminal on the cable head or connecting a crystal oscillator to the OSC1 and OSC2 terminals.  
When a crystal oscillator is inserted into the OSC1 and OSC2 terminals for the system clock,  
the clock is generated by the oscillator circuits shown in figure 9. To input an external clock  
from the user system, input clock pulses satisfying the specifications described in the MCU  
hardware manual into the OSC1 terminal. The system clock (φ) frequency is half of the  
external clock frequency.  
To use the external clock on the user system as the subclock  
Select target clock sub t with the CLOCK command (emulator command). Supply the  
external clock from the user system to the emulator. To input an external subclock from the  
user system, input clock pulses satisfying the specifications shown in figure 9 into the X1  
terminal. The oscillator circuits on the user system interface cable cannot generate external  
subclock pulses by using the crystal oscillator connected to the user system.

4. The P60 to P67 pins are CMOS large-current ports in the MCU, but in the emulator, they are  
normal ports. However, when this user system interface cable is used, a large current of IOL  
10.0 mA (max.) can be output from the ports by changing the P5 jumper setting. Note that when  
the jumper is set to the large-current mode, the P60 to P67 pins become output ports.

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 HS3L08EPI60H 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 11.

6. The flash memory functions of the H8/3644 series are not supported by the emulator. Therefore,  
do not apply 12 V to Vpp/P90 and TEST pins. If 12 V is applied, the emulator will detect it as  
the test mode. The Vpp/P90 and TEST pins have circuits for protection against 12-v application,  
as shown in figure 12.
