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 TP1 terminal pin of the IE-789831-NS-EM1 (the same applies when the voltage is 5 V).

Set the target voltage to between 2.7 and 5.0 V.

For how to select the operating power supply, refer to the ID78K Series Ver.2.30 or Later Operation Windows-

Based User’s Manual (U15185E).

3.4 Clock Settings

3.4.1 Overview of clock settings

The main system clock and subsystem 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 the 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 3-3.

During emulation, the oscillator that is mounted on the target system is not used. Instead, the clock that is mounted

on the emulation board installed in the IE-78K0S-NS or IE-78K0S-NS-A is used.

If the target system includes an external clock, select either (1) Clock that is already mounted on emulation

board, (2) Clock that is mounted by user, or (3) Pulse input from target system.

For the 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 pulse from the target system. There is no need to

supply a clock to the X2 and XT2 pins. Also, even if a crystal resonator is connected directly to

X1 (for the main system clock) or XT1 (for the subsystem clock), the target device will not

operate.

3.5 External Trigger

To set an external trigger, connect the IE-789831-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.

For the use methods, see the ID78K Series Ver.2.30 or Later Operation Windows Based User’s Manual

(U15185E).

(1) EXTOUT

The EXTOUT pin on the IE-789831-NS-EM1 outputs a low level for 1.3

s when a break event occurs.

Caution Connect a pull-up resistor on the target system because this is an open drain output.

(2) EXTIN

An event signal can be input from the EXTIN pin on the IE-789831-NS-EM1. Input a high-level pulse signal for 2

CPU operation clocks or more.

CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICE AND TARGET INTERFACE CIRCUIT

This chapter describes differences between the target device’s signal lines and the signal lines of the target

interface circuit of the IE system.

The target interface circuit of the IE system realizes emulation via an emulation circuit configured by an emulation

CPU, TTL, CMOS-IC, and other components. The electrical characteristics are different from those of the target

device because a protector and other circuits are provided.

(1) Signals input to or output from the emulation CPU

(2) Signals input from the target system via a gate

(3) LCD-related signals

(4) Other signals

The IE-789831-NS-EM1’s circuit is used as follows for signals listed in (1) to (4) above.

(1) Signals input to or output from the emulation CPU

The following signals perform the same operations as in the

PD789830 and the

PD78F9831. However, a 1 Ω

pull-down resistor and 100 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

(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

PD789830 and the

PD78F9831. Their AC characteristics and DC characteristics are therefore different from the

PD789830 and

the

PD78F9831 making it necessary to observe a stricter timing design than in the

PD789830 and the

PD78F9831.

•RESET signal

•Signals related to clock input

In all the signals input from the target system, the RESET signal and signals related to clock input are input to

the emulation CPU via a logic IC. The DC characteristics are therefore different from the

PD789830 and the

PD78F9831.

CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICE AND TARGET INTERFACE CIRCUIT

User’s Manual U14202EJ2V0UM

(3) LCD-related signals

Because the following signals input/output LCD-related signals, special processing is not performed in the IE-

789831-NS-EM1.

•Common pins (COM0 to COM15)

•Segment pins (S0 to S31)

•Port 5 (alternately functions as P50 to P57/S32 to S39)

(4) Other signals

•VDD pin

When the emulation CPU is operating at 5 V, its power is supplied from the IE-789831-NS-EM1, 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 (TVCC) in the IE-789831-NS-EM1 that monitors the input of the target system's

power supply.

•VSS pin

The VSS pin is connected to GND in the IE-789831-NS-EM1

•TEST/VPP pin

The TEST/VPP pin is not used in the IE-789831-NS-EM1.

•X2, XT2 pins

The X2 and XT2 pins are not used in the IE-789831-NS-EM1.
