(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, which is installed in the IE-78K0S-NS or IE-78K0S-NS-A is used. If the target system includes an external clock, select (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 clock from the target. There is no need to supply a clock to X2 or XT2 pin. Figure 3-3.

Its frequency is 5.0 MHz. Figure 3-4.

(2) Clock that is mounted by user The user is able to mount any clock supported by the set specifications on the IE-789046-NS-EM1. Mount either the parts board on which the resonator to be used is mounted or an oscillator on the IE-789046-NS-EM1. This method is useful when using a different frequency from that of the premounted clock. Figure 3-5.

Remark The IE-789046-NS-EM1 is shipped, the settings for “when using clock that is already mounted on emulation board” are preset. (1) When using clock that is already mounted on emulation board When the IE-789046-NS-EM1 is shipped, a 5.0 MHz crystal oscillator is already mounted in the IE-789046-NSEM1’s X1 UMCLK 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). User’s Manual U14433EJ2V0UM 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 TP1 terminal pin of the IE-789046-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 3-13.

(1) EXTOUT Output a low level from the EXTOUT pin on the IE-789046-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-789046-NS-EM1. Use a high-level pulse signal for 2 CPU operation clocks or more for the event signal. XTC1 Figure 3-14.

User’s Manual U14433EJ2V0UM 35 CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS This chapter describes the differences in electrical specifications between the target device and the target interface circuit. Unlike the target device, the target interface circuit of the IE system comprises emulation circuits such as the emulation CPU, TTL, and CMOS-IC and other circuits. Also, because the target interface circuit includes protection and other circuits, its electrical specifications differ from those of the target device. 4.1 µPD789046 Subseries When debugging the µPD789046 Subseries, connect the target system to IE-789046-NS-EM1 via the emulation probe. (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 input to or output from the evaluation chip and peripheral evaluation chip The following signals perform the same operations as in the µPD789046 Subseries. However, a 1 MΩ 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 signals show a delay compared to the µPD789046 Subseries. • RESET signal • X1, XT1 signal 36 User’s Manual U14433EJ2V0UM CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS (3) Other signals • VDD0 and VDD1 pins The emulation CPU operates on the internal power supply voltage (5 V) when the target system is not connected. When the target system is connected, power is supplied via the power supply pin (TP1). The VDD0 and VDD1 pins of the target system are only used to control the LED1 in the IE-789046-NS-EM1 that monitors the input of the target system’s power supply (TVCC). • VSS0 and VSS1 pins The VSS0 and VSS1 pins are connected to GND in the IE-789046-NS-EM1. • TEST/VPP pin The TEST/VPP pin is not used in the IE-789046-NS-EM1. • X2 and XT2 pins The X2 and XT2 pins are not used in the IE-789046-NS-EM1.
