IMPORTANT

Notes on Differences between an Actual MCU and the Emulator:

•Emulator operation differs from emulation 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 ROM and RAM capacities, etc.

(4) Electrical characteristics

(5) Operation in the RAM backup mode

(6) Operation of the watchdog timer function

(7) Port I/O Timing

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

be sure to perform board-mounted evaluation with an ES (Engineering Sample) version MCU to

make final confirmation of device operation before starting mask production.

Note on the Target System:

•Make sure that the target's supply voltage specification 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 a warp of the cable. The warp may cause

breaking the wire.
