4.2 Differences between the Actual MCU and Emulator
Differences between the actual MCU and emulator are shown below. When debugging the MCU using this product, be careful
about the following precautions.

Notes on Internal Memory (ROM, RAM):
Note on Unused Area:
Notes on RESET# Input:
Note on NMI* Input:
Notes on Maskable Interrupts:
Note on Oscillator Circuit:
Note on A/D Converter:
Note on Power-on Reset & Low-voltage Detection Circuit Functions:
The evaluation MCU mounted on this product has RAM of 6 KB and flash ROM of 128 KB. For this reason,
the nonexistent ROM or RAM area of the target MCU may be accessed.
With this product, the flash ROM area of target MCU is cleared at "0000h (NOP instruction)" when starting up
the emulator.
You cannot use unused areas. Write signals to the areas will be ignored, and values read will be undefined.
A low input to pin RESET# from the user system is accepted only when a user program is being executed
(when the RUN status LED on the emulator's upper panel is lit).
The time for starting up (0.2 Vcc to 0.8 Vcc) and falling edge (0.8 Vcc to 0.2 Vcc) for RESET# pin should be
set to 1 μs or less.
A low input to pin NMI* from the user system is accepted only when a user program is being executed (only
while the RUN status LED on the emulator's upper panel is lit).
Even if a user program is not being executed (including when run-time debugging is being performed), the
evaluation MCU keeps running so as to control the emulator. Therefore, timers and other components do not
stop running. If a maskable interrupt is requested when the user program is not being executed (including
Internal I/O access when run-time debugging is being performed), the maskable interrupt request cannot be
accepted, because the emulator disables interrupts. The interrupt request is accepted immediately after the user
program execution is started.
Take note that when the user program is not being executed (including Internal I/O access when run-time
debugging is being performed), a peripheral I/O interruption is not accepted.
Make note of the fact that in the oscillator circuit where a resonator is connected between OSC1 and OSC2,
oscillation does not occur because a converter board is used between the evaluation MCU and the user system.
For notes on when using the oscillator circuit on the user system, refer to "2.9.3 Selecting Clock Supply " (page
35). It is same for a sub-clock oscillator (X1 and X2).
On-chip oscillator function is not supported.
Because a converter board and other devices are used between the evaluation MCU and the user system, the
A/D converter operates differently from that of the actual MCU.
These functions are not supported.
