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

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).

3.1 Connection
(1) Connection with IE-78K0S-NS or IE-78K0S-NS-A main unit
See the IE-78K0S-NS User’s Manual (U13549E)Note for a description of how to connect the IE-789136-NS-EM1
to the IE-78K0S-NS.
Note When using the IE-78K0S-NS-A, refer to the IE-78K0S-NS-A User’s Manual (U15207E).
(2) Connection with emulation probe
See the IE-78K0S-NS User’s Manual (U13549E)Note for a description of how to connect an emulation probe to
the IE-789136-NS-EM1.
On this board, connect an emulation probe to CN2.
Note When using the IE-78K0S-NS-A, refer to the IE-78K0S-NS-A User’s Manual (U15207E).

3.2 Clock Settings
3.2.1 Overview of clock settings
The system clock 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 that is 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 of 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 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
X2 pin.
