User's Manual U16115EJ2V0UM 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, supply the same voltage as that of the target system to the TP1 terminal pin of the IE-789306-NS-EM1 (the same applies when the voltage is 5 V). Set the target voltage to between 1.8 and 5.0 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 TP1 1.8 to 5.0 V: Approximately 100 mA Table 3-3.

Remark The VDD pin on the target system is exclusively used to control LED1 (USER VDD) that monitors whether the power supply of the target system is connected in the IE-789306-NS-EM1. User's Manual U16115EJ2V0UM 21 CHAPTER 3 3.4 INSTALLATION Clock Settings 3.4.1 Overview of clock settings The main system clock and subsystem clock to be used during debugging can be selected from (1) to (3) below. (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 main 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 and XT2 pins. Also, even if a crystal resonator is connected directly to X1 (for the main system clock) or XT1 (for the subsystem clock), the target device will not operate. When emulating the PD789316 Subseries, RC oscillation cannot be used. Figure 3-3.

User's Manual U16115EJ2V0UM 23 CHAPTER 3 INSTALLATION (2) Clock that is mounted by user The user can mount any clock supported by the set specifications on the IE-789306-NS-EM1. This feature is effective when debugging at a different frequency than the clock already mounted. (a) Main system clock 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.

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-789306-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. 34 User's Manual U16115EJ2V0UM 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. The following signals operate the same as in the PD789306/789316 Subseries. * S0 to S23 * COM0 to COM3 * CAPH, CAPL * VLC0 to VLC2 Note that for the following signals, a 1 M pull-down resistor and a 100 resistor are connected in series. Signals related to ports 0 and 1 are connected to a 1 M pull-down resistor in the IE-78K0S-NS or IE-78K0SNS-A. * Signals related to port 0 * Signals related to port 1 * Signals related to port 2 * Signals related to port 3 A 33 k pull-up resistor is connected to the following signals by setting the switch. * Signals related to port 5 Figure 4-1.

In the IE-789306-NS-EM1, the VDD pin of the target system is exclusively used for controlling LED1 (USER VDD), which monitors whether the power of the target system is on. * VSS pin The VSS pin is connected to GND in the IE-789306-NS-EM1. * IC/VPP pin The IC/VPP pin is not used in the IE-789306-NS-EM1.
