Terminology

Some specific words used in this user's manual are defined as follows:

Emulator system

This means an emulator system built around the PC4701 emulator. The PC4701 emulator system is
configured with an emulator main unit, emulation pod, pod probe, host machine and emulator
debugger.

Emulator main unit (Hereafter PC4701)

This means the generic name for emulators for 8 and 16-bit MCUs. For details on specific models
of PC4701, visit Renesas Tools Homepage at http://www.renesas.com/en/tools

Emulation pod main unit

This means the emulation pod M30200T-RPD-E for the M16C/20 Series MCUs.

Pod probe

This means pod probe M30220TF-PRB (this product) for the M30220 and M30221 Groups.

Host machine

This means a personal computer used to control the emulator and emulation pod.

Emulator debugger

This means a software tool M3T-PD30 to control the emulator from the host machine through an
interface.

Firmware

Program that analyzes contents of communication with the emulator debugger and controls the
emulator hardware. This program is installed in the EEPROM in the emulator main unit. This
program is downloadable from the emulator debugger to upgrade the firmware or to support other
MCUs.

Software break

A software break is a function to break the program before the system executes an instruction at the
specified address. The instruction at the preset address will not be executed.

Hardware break

A hardware break is a function to break the program when the system detects a write/read of data to/
from memory or a rise/fall edge of the signal entered from the external trace cable. The former break
function is called address break; and the latter break function is called trigger break. While the
instruction at the address where the software break is set is not executed, a hardware break is
performed after the specified instruction is executed.

Evaluation MCU

This means the MCU mounted on the pod probe which is operated in the specific mode for tools.

Target MCU

This means the MCU you are going to debug.

Target system

This means a user's application system using the MCU to be debugged.

Chapter 1. Precautions for Safety

In both the user's manual and on the product itself, several icons are used to insure proper handling
of this product and also to prevent injuries to you or other persons, or damage to your properties.

( 8 / 54 )

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.

(3) Oscillator circuit

• Make note of the fact that in the oscillator circuit where an oscillator is connected between
the XIN and XOUT 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 (XCIN and XCOUT ).

• 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) XOUT pin

The XOUT pin is not assigned to the evaluation MCU used by this product. For this reason, the
XOUT 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.

FFFF4h - FFFF7h Indefinite

FFFECh - FFFEFh Indefinite

FFFE4h - FFFE7h Indefinite

*1 Interrupts used for the debugger only
(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.

(7) D-A conversion

The characteristics of D-A 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 D-A converter with the actual MCU.

( 9 / 54 )

IMPORTANT

Note on Clock Supply to the MCU:

• Clock can be supplied to the evaluation MCU in one of the following two ways. This is determined
by emulator debugger clock selection.

(1) When "Internal" is selected:

The clock generated by the oscillation circuit in the emulation pod is supplied to the evaluation
MCU. The clock is continually supplied to the evaluation MCU regardless of "the state of
target system clock" and "the state of target program execution".

(2) When "External" is selected:

Clock supply to the evaluation MCU depends on the state of oscillation (oscillate/off) of the
target system.

Notes on Interrupts:

• Even while the target program is not being executed (i.e., even when the target program is paused
or while debug programs are running), the evaluation MCU is operating for controlling debug
programs. Therefore, take note that timers and other functions do not come to a halt when the target
program is not executed.

•If a maskable interrupt is requested while a target program is not being executed (when the target
program is paused or while debug programs are running), the interrupt is not accepted, because the
emulator disables maskable interrupts. If a maskable interrupt is requested while a target program
is not being executed and the program allow the interrupt, the interrupt is accepted immediately
after the target program execution is started.

Notes on DMA Transfer:

• If a DMA request occurs by a timer or other source when the target program is not being executed
(i.e., even when the target program is paused or while debug programs are running), DMA transfer
is executed.

• Make note of the fact that DMA transfer while the target program is stopped may not be performed
correctly.

• Note that the below registers are changed if DMA transfer is generated even when not executing
the target program.

DMA0 transfer counter register: TCR0
DMA1 transfer counter register: TCR1
DMA0 control register: DM0CON
DMA1 control register: DM1CON

Notes on NMI* Input:

• NMI* input from the target system is accepted only while a target program is being executed (i.e.,
only while the RUN status LED on the PC4701's front panel is lit).

• The NMI* interrupt is generated in the following situations.

(1) Immediately after the NMI* pin changes from "H" to "L" level during target program

execution

(2) Immediately after the reset from the target system is released with the NMI* pin "L" level

during target program execution

(3) Immediately after program execution starts with the NMI* pin "L" level, following the reset

is input from the debugger software or emulator

(4) Immediately after program execution starts with the NMI* pin "L" level, when the NMI* pin

is "H" level immediately before the target program stops

( 10 / 54 )

IMPORTANT

Notes on Referencing and Setting the Work Area:

• When using this product, set a start address of the work area to "2C00h" at the time of starting up
the emulator debugger (set by "F/W and Work Area" tab*1 of Init dialog). In this case, the emulator
system uses the area below as a work area.

02C00h - 02C0Fh: Work area

*1 Supported by M3T-PD30 Ver.4.00 or later

•When using the custom command "fmcr1set" (see "4.2 (2) Custom Command fmcr1set" on page

30), the emulator system uses the area below as a work area for "fmcr1set".

02C10h - 02C1Ah: Work area for "fmcr1set"

Notes on MAP References and Settings:

•When starting up the M30200T-RPD-E, initial MAP settings are as follows. Use generally the
M30200T-RPD-E in this setting.

00000h - 003FFh: "EXT"
00400h - FFFFFh: "INT" (emulation memory available)

• When debugging the control program for CPU rewrite mode, set the map setting for addresses
E0000h to FFFDFh to "EXT" or "INT", as required. (See Chapter 4.) Be sure to set the map setting
for addresses FFFE0h to FFFFFh to "INT".

Note on Reading SFR Area:

• The following registers cannot be read normally. However, they can be written to normally.

Pull-up control register 2
Key input mode register

Note on Instructions that Access the Single-step Interrupt Vector Area:

• Do not perform the below debugging operations with the single step interrupt vector area (addresses
FFFECh - FFFEFh).

(1) Step execution of instructions that access the single step interrupt vector area
(2) Program execution from the instruction accessing the single step interrupt vector area when

a software breakpoint is set at the instruction

Note on CPU Rewrite Mode:

• For the notes for debugging the control program for CPU rewrite mode, refer to "4.5 Precautions
for CPU Rewrite Mode" (page 37).
