Warning for Use Environment:
• 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.
Pullup control register

* Not pulled up in 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.
