Cautions 1. Keep the pattern length as short as possible. (Do not exceed 100 mm.)
2. VDD of the IE connector is used for detecting whether the target board is powered on.
3. The DCK, DMS, DDI, DDO, and DRST pins may function alternately as general-purpose
ports. Therefore handle these pins in accordance with the specifications of each target
device.
4. Make sure that the signals driven from the IE-V850E1-CD-NW and the signals generated
on the target system do not conflict.
5. FLMD0 is connected only when the target device incorporates flash memory.
6. RESET may be required when both of the following conditions are satisfied.
• DRST of the target device has an alternate function
• The IE-V850E1-CD-NW is connected to a target system that only uses the POC reset
function, without using the RESET pin function
7. Supply the on-chip debug power supply for VDD.

Interface Signals
This section describes the interface signals.
3.2.1 DRST
This is the reset input signal for the on-chip debug unit. This is a negative logic signal for initializing the debug
control unit asynchronously. Barring a problem arising from the specifications of the target device, pull down this
signal to low level.

74LV125A
Upon detection of VDD of the target system following integrated debugger startup by the IE-V850E1-CD-NW, the
DRST signal changes from low level to high level to start the on-chip debug unit of the target device.
The change of the DRST signal from low level to high level also resets the CPU.
When debugging is started by starting up the integrated debugger, CPU reset always occurs.
3.2.2 DCK
This is the clock input signal. This signal supplies a 20 MHz clock from the IE-V850E1-CD-NW. The DMS and DDI
signals are sampled in synchronization with the rising edge of the DCK signal in the on-chip debug unit, and the data
DDO signal is output in synchronization with the falling edge of the DCK signal. Barring a problem arising from the
specifications of the target device, pull up this signal to high level.

CHAPTER 3 NOTES ON TARGET SYSTEM DESIGN
3.2.3 DMS
This is the transfer mode selection signal. The state machine in the debug unit changes according to the level of
the DMS signal. This signal is sampled in synchronization with the rising edge of the DCK signal in the on-chip
debug unit.
Barring a problem arising from the specifications of the target device, pull up this signal to high level.
The
connection example for this signal is the same as that shown in Figure 3-3 DCK Pin Connection Example.
3.2.4 DDI
This is the data input signal. This signal is sampled in synchronization with the rising edge of the DCK signal in
the on-chip debug unit.
Barring a problem arising from the specifications of the target device, pull up this signal to high level.
The
connection example for this signal is the same as that shown in Figure 3-3 DCK Pin Connection Example.
3.2.5 DDO
This is the data output signal. This signal is output in synchronization with the falling edge of the DCK signal from
the on-chip debug unit.
Barring a problem arising from the specifications of the target device, pull up this signal to high level.

3.2.6 VDD
This signal is used for detection of VDD of the target system. The interface with the target system (detection range)
is 2.0 V to 5.0 V. If VDD from the target system is not detected, the DRST, DCK, DMS, DDI, FLMD0, and RESET pins
go to a high-impedance state.

CHAPTER 3 NOTES ON TARGET SYSTEM DESIGN
3.2.7 FLMD0
This is the flash mode signal. It is used only when the target device incorporates flash memory.
The flash self-programming function is used for the download function for downloading to the flash memory using
the integrated debugger. The FLMD0 pin must be made high level during flash self-programming.
There are two methods for controlling the FLMD0 pin from the IE-V850E1-CD-NW. Either one can be selected for
use.
<1> Control from IE-V850E1-CD-NW
Connect the FLMD0 pin from the IE-V850E1-CD-NW to the FLMD0 pin of the target device.
In the normal mode, nothing is driven from the IE-V850E1-CD-NW.
When, during a break, the download function, etc., of the integrated debugger is executed, the FLMD0 pin
from the IE-V850E1-CD-NW is controlled to be high level. Barring a problem arising from the specifications,
pull down the FLMD0 pin to low level.

<2> Control from port
Connect an unused port of the target device to the FLMD0 pin.
The same port pin (PORT in Figure 3-7) can be used with no problem to realize the flash self-programming
function in the user program using a similar method. Barring a problem arising from the specifications, pull
down this pin to low level.
Perform settings to make the port pin high level prior to executing the download function and make the port
pin low level or high impedance after executing the download function, through the integrated debugger
console.

3.2.8 RESET
This is the system reset input signal. If the DRST pin of target device is an alternate-function pin, DRST can be
enabled/disabled by the value of the OCDM0 bit in the device. Some devices have specifications such that the initial
status of the alternate-function pin varies according to the reset source, so that in the case of reset via the RESET
pin, DRST is enabled when OCDM0 = 1, and in the case of reset via POC (Power-On Clear function), DRST is
disabled when OCDM0 = 0.
In the case of a target system where only reset via POC is used in such a device, DRST cannot be enabled, and
therefore on-chip debugging cannot be performed. In such a case, the DRST pin is enabled by performing the
connection shown in Figure 3-8 and applying reset via the RESET pin from the IE-V850E1-CD-NW.

APPENDIX C INTERNAL ROM/FLASH MEMORY SECURITY FUNCTION
A ten-byte ID code authentication function is provided in the microcontrollers with internal ROM/flash memory to
prevent the memory contents from being read by an unauthorized person.
The ID code specifications are as follows. Embed the ID code in the internal ROM/flash memory in accordance
with these specifications. Input the ID code in the Configuration dialog box of the integrated debugger to execute ID
code authentication before starting debugging (reading the code of the internal ROM/flash memory of the target
device) using the integrated debugger and the IE-V850E1-CD-NW.
[ID code specifications]
• Addresses 0x70 to 0x79 are used as the 10-byte ID code.
• Bit 7 at address 0x79 is used as the N-Wire emulator use enable flag (use disabled if “0”, and enabled if “1”).
• Debugging can be started if the ID code input in the integrated debugger and the ID code embedded in the
internal ROM/flash memory match.
• Even if the ID code matches, debugging cannot be performed if the N-Wire emulator use enable flag is “0”.
• When the flash memory is in the erase status, the ID code is 0xFFFFFFFFFFFFFFFFFFFF.
An example of the ID code setting is shown below.
