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 from Actual MCUs:

• Operations of the emulator system differ from those of mask 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 memory can
read and write in areas other than the SFR, internal RAM and internal ROM.

(3) Oscillator circuit

• Make note of the fact that in the oscillator circuit where a resonator 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

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.
