IMPORTANT
Note on Final Evaluation:
• Be sure to evaluate your system and make final confirmation with an CS (Commercial Sample)
version MCU.
Note on Differences between Actual MCU and Emulator:
• Operations of the emulator system differ from those of actual MCUs as listed below.
(1) Initial values of internal resource data at power-on
(2) Internal memories (ROM and RAM) capacities, etc.
With this emulator system, "INT" (emulation memory ON) is the default for mapping areas
other than the SFR area (addresses 000h - 3FFh). For this reason, the emulation memories can
be read and written into in an area other than the SFR, internal RAM or internal ROM area.

be read and written into in an area other than the SFR, internal RAM or internal ROM area.
(3) Oscillator circuit
• Make note of the fact that in the oscillator circuit where an oscillator is connected between
the X
IN
and X
OUT
pins, oscillation does not occur because a flexible cable, buffer IC and other
devices are used between the evaluation MCU and the target system. It is same for sub-clock
oscillator circuits (X
oscillator circuits (X
CIN
and X
COUT
).
• For note on when using the oscillator circuit on the target system, refer to "4.2 (2) Using
target system's oscillator" (page 21) of the M30200T-RPD-E User's Manual.
(4) X
OUT
pin
The X
OUT
pin is not assigned to the evaluation MCU used by this product. For this reason, the
X
OUT
pin of this product is open.
(5) DBC, single-step and BRK instruction interrupt vector table addresses
It is possible to download to DBC, single-step and BRK instruction interrupt vector table
addresses. However, because the emulator system uses these areas, data different from the
expected value is read out.

(6) A-D conversion
The characteristics of A-D converter differ from those of actual MCU because there are a
flexible cable, pitch converter and other devices between the evaluation MCU and the target
system. Make the final evaluation of the A-D converter with the actual MCU.
