User's Manual U16398EJ1V0UM 19 CHAPTER 3 3.3 INSTALLATION 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, the IE-789088-NS-EM1 is supplied with the same voltage as that of the target system from the VDD pin via the emulation probe, and that voltage is used as the reference voltage for generating the target interface power supply. Set the target voltage to between 1.8 and 5.5 V. For how to select the operating power supply, refer to the ID78K Series Ver.2.30 or Later Operation WindowsBased User's Manual (U15185E). * Maximum current consumption of VDD pin 1.8 to 5.5 V: 20 mA Table 3-3.

(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 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 pin. Also, even if a crystal resonator is connected directly to X1, the target device will not operate. Figure 3-3.

A crystal oscillator (X1) is already mounted on the emulation board. Its frequency is 5.0 MHz. Figure 3-4.

(2) Clock that is mounted by user The user can mount any clock supported by the set specifications on the IE-789088-NS-EM1. This feature is effective when debugging at a different frequency than the clock already mounted. 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 mount the oscillator to be used.

Remark The factory settings of the IE-789088-NS-EM1 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-789088-NS-EM1 is shipped, a 5.0 MHz crystal oscillator is already mounted in the IE-789088-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). User's Manual U16398EJ1V0UM 23 CHAPTER 3 INSTALLATION (2) When using clock mounted by user Perform the settings described under either (a) or (b), 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).

(3) When inputting pulse from target system No hardware settings are required for this situation. When starting the integrated debugger (ID78K0S-NS), open the configuration dialog box and select "External" in the area (Clock) for selecting the CPU's clock source (this selects the user's clock). 26 User's Manual U16398EJ1V0UM CHAPTER 3 3.5 INSTALLATION External Trigger To set an external trigger, connect the IE-789088-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-789088-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-789088-NS-EM1. Input a high-level pulse signal for 2 CPU operation clocks or more. Figure 3-10.

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 directly input to or output from the emulation CPU (2) Signals input from the target system via a gate (3) Other signals The circuits of the IE-789088-NS-EM1 are used as follows for signals listed in (1) to (3) above. The same applies to handling alternate-function pins, for which no circuit is provided in the IE system. 28 User's Manual U16398EJ1V0UM CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICE AND TARGET INTERFACE CIRCUIT (1) Signals directly input to or output from the emulation CPU Refer to Figure 4-1 Equivalent Circuit 1 of Emulation Circuit. Note that for the following signals, a 1 M pull-down resistor and a 100 resistor are connected in series. * Signals related to port 0 * Signals related to port 4 For the following signals, a 100 resistor is connected in series. * Signals related to port 2 Figure 4-1.
