WARNING
Warning for Installation:
• Do not set this product in water or areas of high humidity. Make sure that the main unit does not
get wet. Spilling water or some other liquid into the main unit can cause an unrepairable damage.
Warning for Use Environment:
• This equipment is to be used in an environment with a maximum ambient temperature of 35 °C.
Care should be taken that this temperature is not exceeded.
CAUTION
Cautions to be Taken for This Product:
• Do not disassemble or modify this product. Disassembling or modifying this product can cause
damage. Disassembling and modifying the product will void your warranty.
• Use caution when handling the main unit. Be careful not to apply a mechanical shock.
• Do not pull the emulator probe (100-pin half-pitch cable or 50-pin normal-pitch cable) to
disconnect from the emulator main unit.
•Do not use inch-size screws for this equipment. The screws used in this equipment are all ISO
(meter-size) type screws. When replacing screws, use same type screws as equipped before.

IMPORTANT
Notes on Differences between Actual MCU and Emulator:
• Emulator operation differs from emulation of a mask MCU, as listed below. For details refer to
"Chapter 6. Precautions to be Taken When Debugging".
(1) Reset condition
(2) Initial values of internal resource data at power-on
(3) Internal RAM and ROM capacities, etc.
(4) Electrical characteristics
(5) Operation in the power-down mode
(6) Operation of the watchdog timer function
• Therefore, always be sure to evaluate your system with an evaluation MCU (onetime version).
Also, be sure to perform board-mounted evaluation with ES (Engineering Sample) version MCU
to make final confirmation of device operation before starting mask production.
Note on the Target System:
• The operating voltage of the M34551T2-MCU is +3.0 V or +5.0 V. Therefore the target's supply
voltage should be in the range of +3.0 V ±10 % or 5.0 V ±10 %.
Notes on Connecting the Target System:
• When connecting the emulator probe, be careful to the wrong connection.
•When connecting the emulator probe, be careful to the warp of the cable. The warp may cause
breaking the wire.

2. Handling Precautions
When using the M34551T2-MCU board, pay attention to the following:
(1) About the emulator
To use the M34551T2-MCU board, you always need to install it on the PC4504 emulator main
unit.
(2) About the MCU board installation
Before installing (and removing) the MCU board, always be sure to power off the PC4504
emulator main unit and unplug its power cord from the outlet. For details on how to install and
remove the MCU board, see "Chapter 2. Set-up" in the PC4504 System User’s Manual.
(3) Emulator debugger
When using the M34551T2-MCU board to debug your program, you need to have the M3T-PD45
emulator debugger (sold separately). You need also the data file for 4551/4555 Group included
with M3T-PD45.
(4) Registers that can be operated from M3T-PD45
Table 2.1 lists the registers that can be operated from the M3T-PD45. The "O" in the table means
that the register can be operated; the "X" means that the register cannot be operated.
Table 2.1 Registers that can be operated from M3T-PD45
When setting both bit 3 and bit 0 in the MR clock control register to "0" (high-speed mode, system
clock = f(XIN)), the system clock frequency should be in the following ranges.
•VDD = 3.0 V: XIN≤ 1.0 MHz
•VDD = 5.0 V: XIN ≤ 2.0 MHz
