Target Readers This manual is intended for engineers who will use the IE-780988-NS-EM4 with the IE-
78K0-NS or IE-78K0-NS-A and IE-78K0-NS-P01 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-780988-NS-EM4, refer to not only this manual (supplied with the IE-
780988-NS-EM4) but also the manuals that are supplied with the IE-78K0-NS-P01 and

3.1 Connection
(1) Connection with IE-78K0-NS-P01 and IE-78K0-NS or IE-78K0-NS-A main unit
See the IE-78K0-NS User’s Manual (U13731E) for a description of how to connect the IE-780988-NS-EM4 to the
IE-78K0-NS-P01 and IE-78K0-NS.

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) 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, a resonator is connected to the target device and
the target device’s internal oscillation circuit is used. An example of the external circuit is shown in part (a) of Figure
3-2. During emulation, the resonator that is mounted on the target system is not used. Instead, the clock that is
mounted on the emulation board connected to the IE-78K0-NS or IE-78K0-NS-A is used.
If the target system includes an external clock, select (3) External clock.
For an external clock, a clock signal is supplied from outside the target device and the target device’s internal
oscillation circuit 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. The IE system does not operate if the
crystal resonator is directly connected to X1.

(2) Clock that is mounted by user
The user is able to mount any clock supported by the set specifications on the IE-780988-NS-EM4.
Remove the crystal oscillator (UMCLK) 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.

source (this selects the user’s clock).
Remark When the IE-780988-NS-EM4 is shipped, the settings for “when using clock that is already mounted on
emulation board” are preset.
(1) When using clock that is already mounted on emulation board
When the IE-780988-NS-EM4 is shipped, an 8.38 MHz crystal oscillator is already mounted in the UMCLK socket
of the IE-780988-NS-EM4. When using the factory-set mode settings, there is no need to make any other
hardware settings.
When starting the integrated debugger (ID78K0-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).

(2) When using clock mounted by user
Perform the settings described under either (a) or (b), depending on the type of clock to be used.
When starting the integrated debugger (ID78K0-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).

3.6 Low-Voltage Emulation Setting
When the target system operates on low power voltage, supply the same power supply voltage as that of the target
system to the TP1 terminal pin on the main board (G-780009 board) of the IE-78K0-NS or IE-78K0-NS-A (same as
when the target system is 5 V).
In this case, the power supply voltage of the target system should be in the range of 3.0 to 5.5 V.

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-780988-
NS-EM4 target interface circuit.
Although the target device is a CMOS circuit, the IE-780988-NS-EM4’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 or output from the emulation CPU (
µ
PD7880)
(2) Signals input or output from the emulation CPU (
µ
PD7881)
(3) Other signals
The circuit of the IE system is used as follows for signals listed in (1) to (3) above.
(1) Signals input or output from the emulation CPU (

PD7880)

CHAPTER 5 RESTRICTIONS
The following are the restrictions of the IE-780988-NS-EM4.
(1) When the IE system is started without the target system connected, the initial value of each port is undefined.
Table 5-1. Initial Value of Port When IE System Is Started Without Target System Connected
Emulator Target Device
Initial value of each port Undefined 00H
(2) When emulating the
µ
PD78F0988, the functions related to flash memory, such as the SFR self-write function, are
not supported.
(3) Even if a watchdog timer interrupt (INTWDT) occurs in watchdog timer mode 1 (WDTM3 = 0, WDTM4 = 1), output
from the TO70 to TO75 pins does not stop.
