The information in this document is current as of January, 2002. The information is subject to

change without notice. For actual design-in, refer to the latest publications of NEC's data sheets or

data books, etc., for the most up-to-date specifications of NEC semiconductor products. Not all

products and/or types are available in every country. Please check with an NEC sales representative

for availability and additional information.

liability arising from the use of such products. No license, express, implied or otherwise, is granted under any

patents, copyrights or other intellectual property rights of NEC or others.

Descriptions of circuits, software and other related information in this document are provided for illustrative

purposes in semiconductor product operation and application examples. The incorporation of these

circuits, software and information in the design of customer's equipment shall be done under the full

responsibility of customer. NEC assumes no responsibility for any losses incurred by customers or third

parties arising from the use of these circuits, software and information.

While NEC endeavours to enhance the quality, reliability and safety of NEC semiconductor products, customers

agree and acknowledge that the possibility of defects thereof cannot be eliminated entirely. To minimize

risks of damage to property or injury (including death) to persons arising from defects in NEC

semiconductor products, customers must incorporate sufficient safety measures in their design, such as

redundancy, fire-containment, and anti-failure features.

NEC semiconductor products are classified into the following three quality grades:

"Standard", "Special" and "Specific". The "Specific" quality grade applies only to semiconductor products

developed based on a customer-designated "quality assurance program" for a specific application. The

recommended applications of a semiconductor product depend on its quality grade, as indicated below.

Customers must check the quality grade of each semiconductor product before using it in a particular

application.

"Standard": Computers, office equipment, communications equipment, test and measurement equipment, audio

and visual equipment, home electronic appliances, machine tools, personal electronic equipment

and industrial robots

"Special": Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster

systems, anti-crime systems, safety equipment and medical equipment (not specifically designed

for life support)

"Specific": Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life

support systems and medical equipment for life support, etc.

The quality grade of NEC semiconductor products is "Standard" unless otherwise expressly specified in NEC's

data sheets or data books, etc. If customers wish to use NEC semiconductor products in applications not

intended by NEC, they must contact an NEC sales representative in advance to determine NEC's willingness

to support a given application.

(Note)

(1) "NEC" as used in this statement means NEC Corporation and also includes its majority-owned subsidiaries.

(2) "NEC semiconductor products" means any semiconductor product developed or manufactured by or for

NEC (as defined above).

3.2 Clock Settings

3.2.1 Overview of clock settings

The main system and subsystem clocks to be used during debugging can be selected from (1) to (3) below.

(1) Clock that is already mounted on emulation board

(2) Clock that is mounted by user

(3) Pulse input from target system

If the target system includes a clock oscillator, select either “(1) Clock that is already mounted on emulation board”

or “(2) Clock that is mounted by user”. For the clock oscillator, a resonator is connected to the target device and the

target device’s internal oscillator is used. An example of the external circuit is shown in part (a) of Figure 3-2. During

emulation, the oscillator that is mounted on the target system is not used. Instead, the clock that is mounted on the

emulation board installed in the IE-78K0S-NS or IE-78K0S-NS-A is used.

If the target system includes an external clock, select “(3) Pulse input from target system”.

For the external clock, a clock signal is supplied from outside the target device and the target device’s internal

oscillator is not used. An example of the external circuit is shown in part (b) of Figure 3-2.

Caution The IE system will be hung-up if the main system clock is not supplied normally. Moreover, be

sure to input a rectangular wave as the clock from the target. There is no need to supply a clock

to the X2 pin.

(1) Clock that is already mounted on emulation board

A crystal oscillator is already mounted on the emulation board. Its frequency is 5.0 MHz.

(2) Clock that is mounted by user

The user is able to mount any clock supported by the set specifications on the IE-789177-NS-EM1. Either attach

the parts board on which the resonator to be used is mounted or an oscillator to the IE-789177-NS-EM1. This

method is useful when using a different frequency from that of the premounted clock.

When the IE-789177-NS-EM1 is shipped, a 5.0 MHz crystal oscillator is already mounted in the IE-789177-NS-

EM1’s X1 UMCLK socket. When using the factory-set mode settings, there is no need to make any other

hardware settings.

When starting the integrated debugger (ID78K0S-NS), open the configuration dialog box and select “Internal” in

the area (Clock) for selecting the CPU’s clock source (this selects the emulator’s internal clock).

3.4 Power Supply Voltage Setting of Target Interface

In the IE system, emulation is possible with a voltage of the same level as the power supply voltage of the target

system.

When the target system is not connected, the IE system automatically operates with the emulator’s internal power

supply (5 V). When debugging with a voltage that is the same level as that of the target system, supply the same

voltage as that of the target system to the TP1 terminal pin of the IE-789177-NS-EM1 (the same applies when the

voltage is 5 V). Set the target voltage to between 1.8 and 5.0 V.

Maximum current consumption of TP1

CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS

This chapter describes the differences between the target device’s signal lines and the signal lines of the IE-

789177-NS-EM1’s target interface circuit.

Although the target device is a CMOS circuit, the IE-789177-NS-EM1’s target interface circuit consists of

emulators such as an emulation CPU, TTL, and CMOS-IC.

When the IE system is connected with the target system for debugging, the IE system performs emulation so as to

operate as the actual target device would operate in the target system.

However, some minor differences exist since the operations are performed via the IE system’s emulation.

(1) Signals directly input/output to/from the evaluation chip and peripheral evaluation chip

(2) Signals input from the target system via a gate

(3) Analog signals

(4) Other signals

The IE system’s circuit is used as follows for signals listed in (1) to (4) above.

(1) Signals directly input/output to/from the evaluation chip and peripheral evaluation chip

The following signals perform the same operations as in the

PD789167, 789177 Subseries. However, a 1 MΩ

pull-down resistor and 100 Ω resistor are inserted in series.

• Signals related to port 0

• Signals related to port 1

• Signals related to port 2

• Signals related to port 3

• Signals related to port 5

(2) Signals input from the target system via a gate

Since the following signals are input via a gate, their timing shows a delay compared to the

PD789167, 789177

Subseries.

• RESET signal

• X1, XT1 signals

CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS

User’s Manual U14621EJ2V0UM 37

(3) Analog signals

Because the following signals input/output analog-related signals, special processing is not performed in the IE-

789177-NS-EM1.

• AVDD pin

• AVREF pin

• Signals related to port 6

(4) Other signals

• VDD, VDD1 pins

When the target system is not connected, the internal power supply voltage (5 V) of the IE-789177-NS-EM1 is

supplied to the emulation CPU. When the target system is connected, power is supplied from the voltage

supply pin (TP1). The VDD0, VDD1 pins of the target system are only used to control the LED1 in the IE-789177-

NS-EM1 that monitors the input of the target system’s power supply (TVCC).

• VSS0, VSS1, AVSS pins

The VSS0, VSS1, and AVSS pins are connected to GND in the IE-789177-NS-EM1.

• TEST/VPP pin

The TEST/VPP pin is not used in the IE-789177-NS-EM1.

• X2, XT2 pins

The X2, XT2 pins are not used in the IE-789177-NS-EM1.
