(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, 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 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 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. The IE system does not operate if the crystal resonator is connected to X1 (main system clock) and XT1 (subsystem clock).

(b) For subsystem clock A crystal resonator (X3) is already mounted on the emulation board. Its frequency is 32.768 kHz. Figure 3-4.

User's Manual U14364EJ3V0UM 21 CHAPTER 3 INSTALLATION (2) Clock that is mounted by user The user is able to mount any clock supported by the set specifications on the IE-789418-NS-EM1. (a) For main system clock Remove the crystal oscillator (X2) that is already mounted on the emulation board, and mount either the parts board on which the resonator to be used is mounted or an oscillator. This method is useful when using a different frequency from that of the pre-mounted clock. Figure 3-5.

(b) For subsystem clock Mount the resonator to be used on the parts board (X1) that is already mounted on the emulation board. Alternatively, remove the parts board and mount an oscillator.

Remark When the IE-789418-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-789418-NS-EM1 is shipped, a 5.0 MHz crystal oscillator is already mounted in the IE-789418-NSEM1's X2 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 U14364EJ3V0UM 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-789418-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 3-16.

(1) EXTOUT Outputs a low level from the EXTOUT pin on the IE-789418-NS-EM1 for 1.3 s 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-789418-NS-EM1.

Although the target device is a CMOS circuit, the IE-789418-NS-EM1's target interface circuit consists of emulation circuits such as an emulation CPU, TTL, and CMOS-IC. 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) Analog signals (4) Other signals The IE-789418-NS-EM1's circuit is used as follows for signals listed in (1) to (4) above. (1) Signals input to or output from the EVA chip and peripheral EVA chip The following signals perform the same operations as in the PD789407A, 789417A Subseries. However, a 1 M pull-down resistor and 100 resistor are inserted in series. Refer to Figure 4-1 Equivalent Circuit of Emulation Circuit 1. * Signals related to port 0 * Signals related to port 2 * 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 signals show a delay compared to the PD789407A, 789417A Subseries. Refer to Figure 4-2 Equivalent Circuit of Emulation Circuit 2. * RESET signal * Signals related to X1, XT1 User's Manual U14364EJ3V0UM 37 CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS (3) Analog signals Because the following signals input/output analog signals, special processing is not performed in the IE-789418NS-EM1. Refer to Figure 4-3 Equivalent Circuit of Emulation Circuit 3. * AVDD * AVREF * S0 to S15 * COM0 to COM3 * Port 6 * Port 8 * Port 9 * VLC0 to VLC2 * BIAS (4) Other signals Refer to Figure 4-4 Equivalent Circuit of Emulation Circuit 4. * VDD0 and VDD1 pins The emulation CPU operates on the internal power supply (5 V) of the IE-789418-NS-EM1 when not connected to the target system, and operates on the voltage supplied from the voltage supply pin (TP1) when connected to the target system. The VDD0 and VDD1 pins of the target system are used only to control the LED (TVCC) that indicates whether the target system's power is on or off. * VSS0, VSS1, and AVSS pins The VSS0, VSS1, and AVSS pins are connected to GND in the IE-789418-NS-EM1. * TEST/VPP pin The TEST/VPP pin is not used in the IE-789418-NS-EM1. * X2 and XT2 pins The X2 and XT2 pins are not used in the IE-789418-NS-EM1. 38 User's Manual U14364EJ3V0UM CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS Figure 4-1.
