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.
