3.1 Connection
(1) Connection with IE-78K4-NS main unit
See the IE-78K4-NS User’s Manual (U13356E) for a description of how to connect the IE-784908-NS-EM1 to the
IE-78K4-NS.
(2) Connection with emulation probe
See the IE-78K4-NS User’s Manual for a description of how to connect an emulation probe to the IE-784908-NS-

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) 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 3-2. 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 installed for the IE-78K4-NS.
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 3-2.

(1) Clock that is already mounted on emulation board
A crystal oscillator is already mounted on the emulation board. Its frequency is 12.58 MHz.

Remark The clock that is supplied by the IE-784908-NS-EM1’s oscillator (encircled in the figure) is used.
(2) Clock that is mounted by user
The user is able to mount any clock supported by the set specifications on the IE-784908-NS-EM1. First mount
the resonator on the parts board, then attach the parts board to the IE-784908-NS-EM1. This method is useful
when using a different frequency from that of the pre-mounted clock.

Caution When using an external clock, open the configuration dialog box when starting the integrated

source (this selects the user’s clock).
Remark The IE-784908-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-784908-NS-EM1 is shipped, a 12.58-MHz crystal oscillator is already mounted in the IE-784908-
NS-EM1’s UMCLK socket. When using the factory-set mode settings, there is no need to make any other
hardware settings.
When starting the integrated debugger (ID78K4-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
The settings described under either (a) or (b) are required, depending on the type of clock to be used.
When starting the integrated debugger (ID78K4-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).

When the IE-784908-NS-EM1 is shipped, a 32.768-kHz crystal resonator is already mounted on the IE-784908-
NS-EM1. Pins 6 and 8 on the parts board (USCLK) are shorted. Short pins 1 and 2 on the IE-784908-NS-EM1’s
jumper (JP1). There is no need to make any other settings via the integrated debugger (ID78K4-NS).

The settings described under either (a) or (b) are required, depending on the type of clock to be used. Short pins
1 and 2 on the IE-784908-NS-EM1’s jumper (JP1).
There is no need to make any other settings via the integrated debugger (ID78K4-NS).

3.3 Pin Mask Function Settings
3.3.1 Wait (WAIT) mask function
By setting the DIP switch (SW1) in the IE-784908-NS-EM1, it is possible to mask the alternate function (WAIT)
and HOLD of pin P66 in the
µ
PD784908 Subseries.
Table 3-3. DIP Switch Setting for Wait (WAIT) Mask Function

2 (WAITMS K) 3 (HOLDMSK) 4 (P66ON)
No mask (initial setting) OFF OFF ON
Hold mask status OFF ON OFF

Caution Do not set the DIP switch to settings other than those above.
3.3.2 Wait display function setting
By setting the DIP switch (SW1) in the IE-784908-NS-EM1, it is possible to display the statuses of “waiting” and
“holding” with an LED light.

Caution When pin P66 is used as a port pin, unless the DIP switch is turned OFF the LED may light up.
3.3.3 NMI interrupt mask setting
By setting switch 1 of the DIP switch (SW1) in the IE-784908-NS-EM1, it is possible to mask the NMI interrupt,
which is the alternate function of the port 20.
Table 3-5. DIP Switch Setting for NMI Interrupt Mask
DIP Switch SettingStatus
1 (NMIMSK)
No NMI mask (initial setting) ON
NMI mask status OFF
Caution Because the NMI interrupt is the alternate function of the P20 pin, this pin cannot operate as the
P20 pin when the NMI mask status has been set.

3.4 Low-Voltage Emulation Setting
Low-voltage emulation is possible in the IE system.
When the target system is operating on low voltage, supply the same voltage as the target system to the TP1
terminal pin of the IE-784908-NS-EM1 (this is unnecessary when the TP1 is 5 V). Set the target voltage between 3
and 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-784908-
NS-EM1’s target interface circuit.
Although the target device is a CMOS circuit, the IE-784908-NS-EM1’s target interface circuit consists of an
emulation CPU, TTL, CMOS-IC, and other emulation circuits.
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 directly input/output to/from the emulation CPU
(2) Signals input from the target system via a gate
(3) Other signals
The IE system’s circuit is used as follows for signals listed in (1) to (3) above.
(1) Signals directly input/output to/from the emulation CPU
The following signals perform the same operations as in the
µ
PD784908 Subseries. For the signals related to
ports excluding port 7 (having alternate functions as pins for A/D converter), however, a 1-MΩ pull-down resistor
and 22-Ω resistor are inserted in series.
•Signals related to port 0
•Signals related to port 1
•Signals related to port 2
•Signals related to port 3
•Signals related to port 4
•Signals related to port 5
•Signals related to port 6
•Signals related to port 7 (A/D converter input)
•Signals related to port 9
•Signals related to port 10
•Signals related to A/D converter
•AVREF
•AVSS
•Signals related to PWM
•ASTB/CLKOUT
•IEBusTM interface signal TX, RX
Remark The AVDD pin on the target system is not connected to the IE system. Either the power supply of the IE
system or the power supply supplied to TP1 is supplied to the AVDD pin of the emulation CPU.

(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 that of the
µ
PD784908
Subseries. Their AC characteristics and DC characteristics are therefore different from
µ
PD784908 Subseries,
making it necessary to observe a stricter timing design than in the case of
µ
PD784908 Subseries.

(3) Other signals
• VDD pin
When the emulation CPU is operating at 5 V, its power is supplied from the internal IE system, but when
operating at low voltage, its power is supplied from the low-voltage pin (TP1). The VDD pin of the target system
is only used to control the LED (USERVDD) in the IE system that monitors the input of the target system's power
supply.
• VSS pin
The VSS pin is connected to GND inside the IE system.
