IMPORTANT

Notes on Difference between Actual MCU and Emulator:

• Emulator operation differs from that of a mask MCU as listed below. For details refer to "5.

Precautions to Be Taken When Debugging".

(1) Reset condition
(2) Initial values of internal resource data at power-on
(3) Internal memory (ROM and RAM) capacities, etc.
(4) System clock
(5) Operation of the watchdog timer function
(6) Real-time capability of timer
(7) Operation in power-down mode
(8) Pulldown transistor control
(9) Port I/O timing and characteristics
(10) Low-power detection function

• Therefore, always be sure to evaluate your system with an evaluation MCU (OTP 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.

Notes on Connecting Target System:

• When connecting the target system, be sure to shut OFF the power of the emulator and target

system.

• When connecting the emulator probe, be careful of its orientation.

• When connecting the emulator probe, be careful of a warp of the cable. The warp may cause a break

in the wire.

Note on Target System:

• The operation voltage of the M34282T5-OPT is +3.0 V. Therefore the target's supply voltage

should be in the range of +3.0 V

±10%.

Note on System Clock:

• The maximum operating frequency of the M34282T5-OPT is 4.0 MHz (STCK = f(X

IN

)/8) or 500

kHz (STCK = f(X

IN

)). When the instruction clock is set to f(X

IN

), set the system clock frequency

of the M34282T5-OPT to 500 kHz or less.
