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).

INTRODUCTION
Product Overview The IE-178048-NS-EM1 is designed to be used with the IE-78K0-NS or IE-78K0-NS-A to
debug the following target devices that belong to the 178K Series of 8-bit single-chip
microcontrollers.

Target Readers This manual is intended for engineers who will use the IE-178048-NS-EM1 with the IE-
78K0-NS or IE-78K0-NS-A to perform system debugging.
Engineers who use this manual are expected to be thoroughly familiar with the target
device’s functions and use methods and to be knowledgeable about debugging.
Organization When using the IE-178048-NS-EM1, refer to not only this manual (supplied with the IE-
178048-NS-EM1) but also the manual that is supplied with the IE-78K0-NS or IE-78K0-
NS-A.
The IE-78K0-NS used in combination with the IE-78K0-NS-PA is functionally equivalent
to the IE-78K0-NS-A. In this case therefore, read IE-78K0-NS + IE-78K0-NS-PA for IE-
78K0-NS-A in this document, as necessary.

3.1 Connection
(1) Connection with IE-78K0-NS or IE-78K0-NS-A main unit
See IE-78K0-NS User’s Manual (U13731E) for a description of how to connect the IE-178048-NS-EM1 to the IE-
78K0-NS. See IE-78K0-NS-A User’s Manual (U14889E) for a description of how to connect the IE-178048-NS-
EM1 to the IE-78K0-NS-A.
(2) Connection with 178048 PROBE Board
When using the emulation probe NP-80GK, use the 178048 PROBE Board. Connect CN5 of the IE-178048-NS-
EM1 and CN1 of the 178048 PROBE Board, aligning pin 1 of each.
(3) Connection with emulation probe
See the manual of the in-circuit emulator to be used (IE-78K0-NS User’s Manual (U13731E) or IE-78K0-NS-A
User’s Manual (U14889E)) for a description of how to connect the emulation probe to the IE-178048-NS-EM1.
When using the emulation probe NP-64CW, connect it to CN5 on this board. When using the emulation probe
NP-80GK, connect it to CN2 on the 178048 PROBE Board.
(4) Connection with BNC PROBE
Connect the supplied BNC PROBE to the J1 to J8 connectors on the IE-178048-NS-EM1.
Signals corresponding to J1 to J8 are as follows. Connect to amplify inputs from the target system.
J1: VSYNC J5: B
J2: HSYNC J6: I
J3: R J7: Open (not connected)
J4: G J8: BLANK
Caution Incorrect connection methods may damage the IE system.
Be sure to read the emulation probe’s user’s manual for a detailed description of the correct
connection method.

3.2 Clock Settings
3.2.1 Overview of clock settings
The main 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) External clock
If the target system includes an internal clock, select either (1) Clock that is already mounted on emulation
board or (2) Clock that is mounted by user. For an internal clock, the target device is connected to a resonator
and the target device’s internal oscillator is used. An example of the external circuit is shown in part (a) of Figure 3-3.
During emulation, the resonator that is mounted on the target system is not used. Instead, it uses the clock that is
mounted on the emulation board which is connected to the IE-78K0-NS or IE-78K0-NS-A.
If the target system includes an external clock, select (3) External clock.
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 3-3.
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 X2 pin.
