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.

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.

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 a 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 for 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 an 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. The IE system does not operate if
the crystal resonator is connected to X1 (main system clock) and XT1 (subsystem clock).

(2) Clock that is mounted by user
The user is able to mount any clock supported by the set specifications on the IE-789418-NS-EM1.
(a) For main system clock
Remove the crystal oscillator (X2) that is already mounted on the emulation board, and mount either the
parts board on which the resonator to be used is mounted or an oscillator. This method is useful when
using a different frequency from that of the pre-mounted clock.

3.4 Setting Power Supply Voltage 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-789418-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
1.8 to 5.0 V: Approximately 100 mA

CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS
This chapter describes differences between the target device’s signal lines and the signal lines of the IE-789418-
NS-EM1’s target interface circuit.
Although the target device is a CMOS circuit, the IE-789418-NS-EM1’s target interface circuit consists of
emulation circuits 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 input to or output from the EVA chip and the peripheral EVA chip
(2) Signals input from the target system via a gate
(3) Analog signals
(4) Other signals
The IE-789418-NS-EM1’s circuit is used as follows for signals listed in (1) to (4) above.
(1) Signals input to or output from the EVA chip and peripheral EVA chip
The following signals perform the same operations as in the
µ
PD789407A, 789417A Subseries. However, a 1
MΩ pull-down resistor and 100 Ω resistor are inserted in series. Refer to Figure 4-1 Equivalent Circuit of
Emulation Circuit 1.
•Signals related to port 0
•Signals related to port 2
•Signals related to port 4
•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 signals show a delay compared to the
µ
PD789407A,
789417A Subseries. Refer to Figure 4-2 Equivalent Circuit of Emulation Circuit 2.
•RESET signal
•Signals related to X1, XT1
CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS
User’s Manual U14364EJ3V0UM
38
(3) Analog signals
Because the following signals input/output analog signals, special processing is not performed in the IE-789418-
NS-EM1.
Refer to Figure 4-3 Equivalent Circuit of Emulation Circuit 3.
•AVDD
•AVREF
•S0 to S15
•COM0 to COM3
•Port 6
•Port 8
•Port 9
•VLC0 to VLC2
•BIAS
(4) Other signals
Refer to Figure 4-4 Equivalent Circuit of Emulation Circuit 4.
•VDD0 and VDD1 pins
The emulation CPU operates on the internal power supply (5 V) of the IE-789418-NS-EM1 when not
connected to the target system, and operates on the voltage supplied from the voltage supply pin (TP1) when
connected to the target system.
The VDD0 and VDD1 pins of the target system are used only to control the LED (TVCC) that indicates whether
the target system’s power is on or off.
•VSS0, VSS1, and AVSS pins
The VSS0, VSS1, and AVSS pins are connected to GND in the IE-789418-NS-EM1.
•TEST/VPP pin
The TEST/VPP pin is not used in the IE-789418-NS-EM1.
•X2 and XT2 pins
The X2 and XT2 pins are not used in the IE-789418-NS-EM1.
