3.2 Clock Settings
3.2.1 Overview of clock settings
The system 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, 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 3-2.
During emulation, the oscillator that is mounted on the target system is not used. Instead, the clock that is mounted
on the emulation board which 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. However, it is not necessary to supply a
clock to the X2 pin.

(2) Clock that is mounted by user
The user is able to mount any clock supported by the set specifications on the IE-789801-NS-EM1. First mount
the resonator on the parts board, then attach the parts board to the IE-789801-NS-EM1. This method is useful
when using a different frequency from that of the pre-mounted clock.

Remark The IE-789801-NS-EM1’s factory settings are those listed above under “when using clock that is already
mounted on emulation board”.
(1) When using clock that is already mounted on emulation board
When the IE-789801-NS-EM1 is shipped, a 6 MHz crystal oscillator is already mounted in the IE-789801-NS-
EM1’s X1 socket. If the IE-789801-NS-EM1 is in the same state as when shipped, no hardware settings are
required.
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).

3.3 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 TM1 terminal pin of the IE-789801-NS-EM1 (the same applies when the voltage is 5 V).
Set the target voltage to between 4.0 and 5.0 V.
•Maximum current consumption of TM1
4.0 to 5.0 V: Approximately 100 mA

3.4 External Trigger
To set up an external trigger, connect it to the IE-789801-NS-EM1’s check pins EXTOUT and EXTIN as shown
below.
See the IE-78K0S-NS User’s Manual (U13549E) or IE-78K0S-NS-A User’s Manual (U15207E) for pin
characteristics, and the ID78K0-NS, ID78K0S-NS Integrated Debugger Ver. 2.20 or Later Operation User’s
Manual (Windows Based) (U14910E) for usage methods.
(1) EXTOUT
Output a low level from the EXTOUT pin on the IE-789801-NS-EM1 for 1.3
µ
s upon the occurrence of a break
event.
Caution Connect a pull-up resistor on the target system since this is an open-drain output.
(2) EXTIN
An event signal can be input from the EXTIN pin on the IE-789801-NS-EM1. Use a high-level pulse signal of 2
CPU operation clocks or more for the event signal.

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-789801-
NS-EM1’s target interface circuit.
Although the target device is a CMOS circuit, the IE-789801-NS-EM1’s target interface circuit consists of an
emulation chip, TTL, CMOS-IC, and other components.
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) Other signals
The IE-789801-NS- EM1’s circuit is used as follows for signals listed in (1) to (3) above.
CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS
User’s Manual U13390EJ2V0UM 33
(1) Signals input to or output from the EVA chip and the peripheral EVA chip
The following signals perform the same operations as in the
µ
PD789800 Subseries.
•Signals related to port 0
•Signals related to port 1
•Signals related to port 2
•Signals related to port 4
•Signals related to USB
(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
µ
PD789800
Subseries.
•RESET signal
•Signals related to clock input
(3) Other signals
•VDD pin
The emulation CPU operates with the internal power supply of the IE system (5 V) when not connected to the
target system, and operates with the voltage (LVCC) supplied from the voltage supply pin (TM1) when
connected to the target system.
The VDD pin of the target system is used only for control of LED1 (USER VDD), which indicates whether the
target system’s power is on or off.
•VSS pin
The VSS pin is internally connected to GND in the IE-789801-NS-EM1.
•VPP/IC pins
These are not used for the IE-789801-NS-EM1
•X2 pin
This is not used for the IE-789801-NS-EM1.
