(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 3-2. During emulation, the oscillator that is mounted on the target system is not used. Instead, the clock that is mounted on the emulation board installed in 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 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 3-2. 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 clock from the target. There is no need to supply a clock to the X2 pin. Figure 3-2.

Its frequency is 5.0 MHz. Figure 3-3. When Using Clock That Is Already Mounted on Emulation Board IE-78K0S-NS or IE-78K0S-NS-A Target system IE-789026-NS-EM1 Mounted oscillator (to be used) Emulation probe Clock oscillator or external clock (not used) Remark The clock that is supplied by the IE-789026-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-789026-NS-EM1. Remove the crystal oscillator (X1) that is already mounted on the emulation board, and mount the parts board on which the resonator to be used is mounted or the oscillator to be used. This method is useful when using a different frequency from that of the pre-mounted clock. Figure 3-4.

Remark The IE-789026-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-789026-NS-EM1 is shipped, a 5.0-MHz crystal oscillator is already mounted in the IE-789026-NSEM1’s X1 socket. When using the factory-set mode settings, there is no need to make any other hardware settings. 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). 22 User’s Manual U14362EJ2V1UM 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 TP1 terminal pin of the IE-789026-NS-EM1 (the same applies when the voltage is 5 V). Set the target voltage to between 1.8 and 5.0 V. • Maximum current consumption of TP1 1.8 to 5.0 V: Approximately 100 mA Figure 3-9.

User’s Manual U14362EJ2V1UM 29 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 IE-789026NS-EM1’s target interface circuit. Although the target device is a CMOS circuit, the IE-789026-NS-EM1’s target interface circuit consists of an emulation CPU, 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 evaluation chip and peripheral evaluation chip (2) Signals input from the target system via a gate (3) Other signals The IE-789026-NS-EM1’s circuit is used as follows for signals listed in (1) to (3) above. (1) Signals input to or output from the evaluation chip and peripheral evaluation chip The following signals perform the same operations as in the µPD789026 Subseries. However, a 1 MΩ pull-down resistor and 100 Ω resistor are inserted in series for the signals related to ports. Refer to Figure 4-1 Equivalent Circuit 1 of Emulation Circuit. • 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 (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 µPD789026 Subseries. • RESET signal • X1 signal Refer to Figure 4-3 Equivalent Circuit 3 of Emulation Circuit. 30 User’s Manual U14362EJ2V1UM CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICE AND TARGET INTERFACE CIRCUIT (3) Other signals • VDD pin When the target system is not connected, the internal power supply voltage (5 V) of the IE-789026-NS-EM1 is supplied to the emulation CPU. When the target system is connected, power is supplied via the voltage supply pin (TP1). The VDD pin of the target system is only used to control the LED (TVCC) in the IE-789026NS-EM1 that monitors the input of the target system's power supply. • VSS pin The VSS pin is connected to GND in the IE-789026-NS-EM1. • VPP/IC pin The VPP and IC pins are not used in the IE-789026-NS-EM1. • X2 pin The X2 pin is not used in the IE-789026-NS-EM1.
