(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. Figure 3-2.

Its frequency is 6 MHz. Figure 3-3.

(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-NSEM1’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). User’s Manual U13390EJ2V0UM 23 CHAPTER 3 INSTALLATION (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 (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).

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 Figure 3-9.

Remark The VDD pin of the target system is only used for controlling LED1 (TVCC), which monitors whether the power supply of the target system is connected in the IE-789801-NS-EM1. User’s Manual U13390EJ2V0UM 29 CHAPTER 3 3.4 INSTALLATION 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 µs 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. Figure 3-10.

User’s Manual U13390EJ2V0UM 31 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-789801NS-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. 32 User’s Manual U13390EJ2V0UM CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS (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 µPD789800 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 µPD789800 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.
