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
1. Confirming the location of IC socket
CAUTION
After confirming the location of pin 1 on the IC socket,
apply epoxy resin adhesive to the end of the four projections
at the bottom of the IC socket, and fasten it to the user
system.
Use the guide pins provided to determine where to install the IC socket, as shown in figure 3.

2. Solder the IC socket for a FP-144 package to the user system.
CAUTION
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.)
2.2.2 Inserting Cable Head
CAUTION
Check the location of pin 1 before inserting.
Align pin 1 on the IC socket for a FP-144 system interface cable head into the IC socket on the user
system, as shown in figure 4.

2.2.3 Fastening Cable Head
CAUTION
1. Use a Philips-type screwdriver whose head matches
the screw head.
2. The tightening torque must be 0.054 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-144 package on the user
system with the four screws (M2 x10 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 Philips-type screwdriver whose head matches
the screw head.
3. The tightening torque must be 0.054 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 9. After inserting the MCU, fasten the socket cover with the provided four screws
(M2 x6 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 E6000 emulator for the H8S/2646 series, turn on the emulator according to the
procedures described in the E6000 Series 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 Emulator Supplementary Information (HS2646EPI61HE).
 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
Select the target clock t or t2 as the system clock (φ), by using the CLOCK command
(emulator command). Supply the external clock from the user system to the emulator by
inputting the external clock from the EXTAL on the cable head or connecting a crystal
oscillator to the EXTAL and XTAL terminals. For details, refer to section 21, Clock Pulse
Generator, in the H8S/2646 F-ZTAT™ Hardware Manual.
Figure 10 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 HS2646EPI61H 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.
