• This equipment is to be used in an environment with a maximum ambient temperature of 35°C. Care
should be taken that this temperature is not exceeded.

CAUTION

Caution to Be Taken for Modifying This Product:

• Do not disassemble or modify this product. Disassembling and modifying the product will void
your warranty.

Cautions to Be Taken for This Product:

• Use caution when handling the main unit. Be careful not to apply a mechanical shock.

• Do not touch the connector pins of the emulator main unit and the target MCU connector pins
directly. Static electricity may damage the internal circuits.

• Do not pull the compact emulator main unit by the serial cable for connecting to the target system.
The cable may cause a break.

•Do not use inch-size screws for this equipment. The screws used in this equipment are all ISO
(meter-size) type screws. When replacing screws, use same type screws as equipped before.

• The part around the power connector J1 (especially, the IC6 regulator) may get hot. Do not touch
it to prevent burn injuries. And, do not apply a voltage other than the specified voltage of the product
(4.5 to 7.0 V), because it may cause burn injuries and the failure of internal circuits.

IMPORTANT

Note on Malfunctions in the System

• If the emulator malfunctions because of interference like external noise, shut OFF power to the
emulator once and then reactivate it.

( 9 / 52 )

IMPORTANT

Notes on Differences between the Actual MCU and Emulator:

•Operations of the emulator differs from those of mask MCUs as listed below.

(1) Reset condition

Set the time for starting up (0.2 to 0.8 Vcc) 1 µs or less.

(2) Data values of RAM and ROM areas at power-on

When power is turned on, the RAM and ROM areas of the emulator are defaulted to 04H.

(3) Register values when power is turned on

When power is turned on, the emulator's register values are defaulted to 0. However, the
program counter is defaulted to the reset vector value (C000016) initially set by the emulator.

(4) Internal memory (RAM and ROM) capacity, etc.

Because the internal memories (RAM and ROM) are emulated by the emulation memory, the
capacity and assignment of the emulator's internal memories differ from those of the actual
MCU. For memory mapping, see "4.2 Memory Map" (page 35).

(5) Characteristics of ports P00 to P57

As ports P00 to P57 are connected via emulation circuits, the electric characteristics etc. differ
from those of actual MCU. The device used for the port emulation circuit is;

Device: M60081L-0142FP

(6) MCU function

Some MCU functions cannot be used in the emulator system. For details, refer to "Note on
MCU Functions That Cannot Be Used with This Emulator" (page 11).

(7) Pullup control register

Operations of the pullup control registers are different from those of actual MCUs.

When pull-up control register 1 for port pins P44 - P47 (bit 1 of address 3FDh: PU11) is set to

"1" (pulled up), port pins P15 - P17 are also pulled up regardless of the setting of pullup control
register 0 for port pins P14 - P17 (bit 3 of address 3FCh: PU03).

However, this problem arises only in the compact emulator and does not arise in actual MCUs.

•As a pitch converter board and other devices are used between the evaluation MCU and the target
system, some characteristics are slightly different from those of the actual MCU. Therefore, be sure
to evaluate your system with an evaluation MCU. Before starting mask production, evaluate your
system and make final confirmation with an ES (Engineering Sample) version MCU.

( 10 / 52 )

IMPORTANT

Note on MCU Functions That Cannot Be Used with This Emulator:

• The following MCU features cannot be used with this emulator.

(1) Debugging cannot be done with this emulator in the memory expansion mode or micropro-

cessor mode.
This emulator is specifically designed for use in the single-chip mode. For this reason,
debugging is not possible in the memory expansion mode or microprocessor mode.

• When using this emulator, normally set the processor mode bit in the processor mode register
to the "single-chip mode".

•When using this emulator, set the CNVSS and BYTE pins to "L" level.

(2) Oscillation circuits that use a resonator cannot be used.

Because a control gate array is situated between the evaluation MCU and the target system,
oscillation circuits that connect a resonator between the XIN and XOUT pins will not oscillate.
The same applies to the sub-clock oscillation circuit (XCIN, XCOUT): oscillation circuits with a
resonator cannot be used. See "3.5 Selecting Clock Supply" (page 29).

(3) Watchdog timers cannot be used.

MCU watchdog timers can only be used during program execution (free running). Disable
watchdog timers in all other program operations (break, dump, forced stop, etc.).

Also, if the target system has a watchdog timer in its reset circuit, disable it, too, when using
the emulator.

(4) The BRK command cannot be used.

The BRK command cannot be used. The vector address of the BRK interrupt is normally
indicated in the emulator work area, and the vector address value cannot be changed.

(5) Single step interrupts cannot be used.

Single step interrupts cannot be used. The vector address of a single step interrupt is normally
indicated in the emulator work area, and the vector address value cannot be changed.

(6) The DBC* interrupt (debug interrupt) cannot be used.

The DBC* interrupt cannot be used. The vector address of the DBC* interrupt is normally
indicated in the emulator work area, and the vector address value cannot be changed.

(7) Software resets cannot be used.

Do not use software resets.

(8) A-D input group select function is unusable.

The A-D input group select function (M16C/62T Group-only function) cannot be used.

(9) Flash memory and EPROM modes are not emulated.

This emulator does not emulate the flash memory and EPROM modes. Also, the emulator
does not emulate the CPU rewrite mode in the flash memory mode.

( 11 / 52 )

IMPORTANT

Notes on Using this Product for Debugging Other than M16C/62A:

• This emulator is equipped with M30622SAFP (M16C/62A Group) as an evaluation MCU and
emulates M16C/62A Group MCUs. In some functions of there are differences between the MCUs
of M16C/62A Group and the MCUs of other than M16C/62A Group.

Therefore when you use this emulator for debugging an MCU of other than M16C/62A Group, be
careful about the differences of functions of each MCU.

For details on the functions of each MCU, see datasheets and user's manuals of each MCU.

• This product cannot be used in the operating frequency and the operating power voltage exceeding
the guaranteed range.

Note on Restrictions in Using the Emulator (1/2):

• The following restrictions apply to this emulator.

(1) Debug command execution when the BCLK is stopped

When the BCLK is stopped, debug commands (break, dump, single-step, forced stop, etc.)
cannot be executed. The BCLK can stop in the following cases.

• When the target clock is not oscillating

• When the target MCU is on hold

• When the target MCU is in the stop mode

(2) MCU status during program hold

With this emulator, the program can be stopped by putting the MCU on hold. Note that, in this
case, peripheral circuits are still operating.

(3) Interrupts during single step execution

Interrupts are disabled during single step execution. Accordingly, interrupt processing is not
performed even if an interrupt request is sent.

(4) Address matched interrupt

Do not set software breaks for an address for which an address matched interrupt is set. In step
execution, do not execute addresses that generate address matched interrupts.

(5) Stop and wait modes

Do not use a single step for the command that shifts to the stop mode. Operation does not shift
to the wait mode when the command that shifts to the wait mode is executed as a single step.

(6) Stack area

With this emulator, user stacks specified by ISP consume 4 bytes. If there isn't enough user
stack area, using other areas not designed for use as stacks (SFR area, RAM area that stored
data or ROM area) can damage the user program or destabilize emulator control. Therefore,
ensure a maximum +4 bytes of the area used by the user program as user stack area.

(7) Trace results for addresses that set software breaks

Software breaks replace the original command with the BRK command that generates the
BRK interrupt. When trace results are viewed in the bus display, "0016" is displayed by
fetching (by command) the address that sets the software break, however in the reverse
assembly display, the "BRK" command is displayed.

(8) Protect register (PRC2)

When the protect register (PCR2) that enables writing in the port P9 direction register and the
SI/O3 and 4 control registers is changed in the following way, the protect is not cancelled.

1) When the "command that sets PRC2 to '1' is executed (step execution)"

2) When the program is executed with a break point set between the "command that sets
PRC2 to '1'" and "when the register to be protected is set"

3) When "PRC2 is set to '1'" in the Dump or Script windows

( 12 / 52 )

IMPORTANT

Note on Restrictions in Using the Emulator (2/2):

• The following restrictions apply to this emulator.
(9) Debug command execution during user program execution

The real-time aspect of the user program is not guaranteed when debug commands such as
dump are executed during user program execution.

(10) DMA transfer

With this product, the program is stopped by putting the MCU on hold. Therefore, if a DMA
request is generated by a timer or other source while the program is stopped, DMA transfer
is executed. However, make note of the fact that DMA transfer while the program is stopped
may not be performed correctly. Also note that the below registers have been changed to
generate DMA transfer as explained here even when the program is stopped.

• DMA0 transfer counter TCR0

• DMA1 transfer counter TCR1

Note on Controlling MCU Pins:

• Some MCU pins are controlled by the emulator.
(1) RESET* input

The RESET* input from the target system is accepted only while a user program is being
executed (only while the RUN status LED of the emulator is lit).

(2) NMI* input

The NMI* input from the target system is accepted only while a user program is being
executed (only while the RUN status LED of the emulator is lit).

Notes on the Target System (power supply, order of powering on):

•When the target system is connected, be sure to set the JP1 of the emulator to "EXT".

• This emulator cannot supply the power to the target system. Therefore design your system so that

the target system is powered separately.

• This emulator consumes max. 500 mA of electric current from the target system.

• The voltage of the target system should be within the range of 3.0 to 5.0 V.

• Before powering on your emulator system, check that the host machine, the emulator, the converter

board and target system are all connected correctly. Next, turn on the power to each equipment
following the procedure below.

(1) Turn ON/OFF the target system and the emulator as simultaneously as possible.
(2) When the emulator debugger starts up, check the target status LEDs on the emulator to see if

this product is ready to operate.

Is the power supplied? : Check that target status LED (POWER) is ON.*
Is the clock supplied? : Check that target status LED (CLOCK) is ON.

*1 When the target system is not connected, the target status LED (POWER) is not lit.

IMPORTANT

Note on Changing the Clock Supply:

•For using XCIN-XCOUT pins, it is necessary to set "P87/XCIN selection switch" of the
emulator to XCIN side. For how to set it, refer to "2.3 (2) P87/XCIN selection switch"
(page 20).

(1) Selecting Clock Supply

To select the clock supply, change the clock by the Clock tab of the Init dialog box when starting up
the emulator debugger or the CLK command input on the Script Window. For details, refer to user's
manual of the emulator debugger.

(1) Selecting by Init dialog box

• Select main clock supply

• Select sub-clock supply

(2) Selecting by CLK command

An example of CLK command input by the script window is shown below.
example 1) When XIN-XOUT (main clock) is supplied from internal (INT) and XCIN-XCOUT

(sub-clock) is supplied from external (EXT)

CLK INT, EXT

example 2) When XIN-XOUT (main clock) is supplied from external (EXT) and XCIN-XCOUT

(sub-clock) is supplied from internal (INT)

CLK EXT, INT

( 29 / 52 )

(2) Using the Oscillator Circuit on the Target System

To operate the compact emulator with the oscillator circuit on the target system, construct the
oscillator circuit as shown in Figure 3.1 in the target system and input the oscillator output at 50%
duty (within the operating range of the evaluation MCU) into the XIN pin. And the XOUT pin should
be open. It is same for sub-clock oscillator (XCIN and XCOUT).

Figure 3.1 External oscillator circuit

Make note of the fact that in the oscillator circuit shown in Figure 3.2 where a resonator is connected
between the XIN and XOUT pins, oscillation does not occur because an emulation circuit is used
between the evaluation MCU and the target system. It is same for sub-clock oscillator circuits (XCIN
and XCOUT).

Figure 3.2 Circuit in which oscillation does not occur (same for XCIN-XCOUT)

( 30 / 52 )

(3) Changing the Internal Oscillator Circuit of Emulator

A ceramic oscillator circuit for 10 MHz is mounted on this product as a oscillator of a main clock
oscillator circuit when shipped from factory. It is possible to change it to the oscillator circuit board
for 16 MHz (included). How to replace it is shown below. Be sure to read IMPORTANT below before
replacing it.

IMPORTANT

Notes on Replacing Internal Oscillator Circuit of Emulator:

• Soldering is required to replace the emulator's internal oscillation circuit. If you are
inexperienced at soldering, it is recommended to supply a clock of arbitrary
frequency from an external source.

• The included 16MHz oscillator is the only oscillator that can be used as a
replacement. Other oscillators may not oscillate properly, therefore supply a clock
of arbitrary frequency from an external source.

• Emulator standalone operation is not guaranteed when a 16MHz oscillator is
installed. During standalone operation, the emulator operates at 3.3 V, which
exceeds the guaranteed operating frequency of the MCU.

• Generally, the oscillator can be replaced only twice (removal and installation count
as one time). Any more than this will effect board pattern durability, it is not
recommended.

• Be careful not to damage other devices when replacing the oscillator. Servicing for
damage incurred during oscillator replacement can be subject to billing even in the
warranty period.

(1) Check the operation of the system

Check that the emulator system has no fault by executing the self-check referring "5.3 When
the Operation of the Emulator is Abnormal" (page 44).

(2) Remove the target connection board

Remove the target connection board on the lower board of the emulator as shown in Figure 3.3.

Apply an equal amount of force to the connectors on each end of the target connection board when pulling the board out.
Note: Do not apply excessive force to the connectors. Excessive force can break the connectors.

Figure 3.3 Removing the target connection board (side view)

( 31 / 52 )

(3) Remove the oscillator

Figure 3.4 shows the position of the oscillator for the main clock. Remove the oscillator using
a soldering iron. Be careful not to break the other part.

Oscillator for
main clock

Figure 3.4 Position of oscillator for main clock
(bottom view after removing target connection board)

(4) Connecting the Oscillator

Solder the included 16MHz oscillator in the place of the older oscillator (see Figure 3.4).
Solder the oscillator so that the label can be read.

(5) Connecting the target connection board

Check the oscillator is properly connected. If it is, connect the target connection board to the
emulator. The connectors are designed so that they cannot be inserted in the opposite
direction, therefore check orientation before inserting the oscillator. Also, insert the oscillator
without applying excessive force.

Insert an equal amount of force to the connectors on each end of the target connection board when inserting the board.
Note: Do not insert excessive force to the connectors. Excessive force can break the connectors.

Figure 3.6 Connecting the target connection board (side view)

Figure 3.5 Removing an oscillator

(6) Check the operation of the system

After connecting the target system, start up the emulator system. If the emulator starts up
normally, the replacement is completed.

IMPORTANT

Notes on Replacing Internal Oscillator Circuit of Emulator:

•When a 16MHz oscillator is installed, the self-check cannot be executed, because it
must be done with the target system not connected. During standalone operation, the
emulator operates at 3.3 V, which exceeds the guaranteed operating frequency of the
MCU.
