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-789436-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 Windows-Based 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-789436-NS-EM1. User's Manual U16283EJ2V0UM 21 CHAPTER 3 INSTALLATION 3.4 Clock Settings 3.4.1 Overview of clock settings The main system and subsystem clocks 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 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 3-3. 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 for 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 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 3-3. 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. The IE system does not operate if the crystal resonator is connected to X1 (main system clock) and XT1 (subsystem clock). Figure 3-3. External Circuits Used as System Clock Oscillator (a) Clock oscillator Target device VSS X1 or XT1 X2 or XT2 X2 or XT2 Crystal or ceramic resonator External clock (b) External clock Target device X1 or XT1 22 User's Manual U16283EJ2V0UM CHAPTER 3 INSTALLATION (1) Clock that is already mounted on emulation board The crystal oscillator mounted on the IE-789436-NS-EM1 can be used. (a) For main system clock A crystal oscillator (X1) is already mounted on the emulation board. Its frequency is 5.0 MHz. Figure 3-4.

(b) For subsystem clock A crystal resonator (XTC1) is already mounted on the emulation board. Its frequency is 32.768 kHz. Figure 3-5.

User's Manual U16283EJ2V0UM 23 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-789436-NS-EM1. This method is useful when using a different frequency from that of the pre-mounted clock. (a) For main system clock Remove the crystal oscillator (X1) 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.

User's Manual U16283EJ2V0UM 31 CHAPTER 3 INSTALLATION 3.5 Mask Option Settings By setting the DIP switch (SW1) in the IE-789436-NS-EM1, a 33 k pull-up resistor can be connected to P50 to P53 by mask option. Use the mask option setting dialog box of the integrated debugger (ID78K0S-NS) to set the mask option. When reading a project file, however, setting is not required. The results of reading a project file are reflected in the mask option setting dialog box. For the usage method, refer to the ID78K Series Ver.2.30 or Later Operation Windows Based Use's Manual (U15185E). Table 3-6. Mask Option Setting SW1 1 Connected to: P50 2 P51 3 P52 4 P53 When the DIP switch is ON, the corresponding pin is pulled-up by the target interface supply voltage (LVCC). When it is OFF, the corresponding pull-up resistor is disconnected. Set the DIP switch to OFF for ports that do not exist. Figure 3-15.

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 proved. (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-789436-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 U16283EJ2V0UM 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 PD789426, PD789436 Subseries. * S0 to S4 * COM0 to COM3 * CAPH, CAPL * VLC0 to VLC2 * Signals related to port 6, AVDD, AVSS * Signals related to port 7 * Signals related to port 8 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.
