User's Manual U14202EJ2V0UM 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-789831-NS-EM1 (the same applies when the voltage is 5 V). Set the target voltage to between 2.7 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 2.7 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-789831-NS-EM1. User's Manual U14202EJ2V0UM 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. Figure 3-3.

User's Manual U14202EJ2V0UM 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-789831-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 UMCLK) 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.

User's Manual U14202EJ2V0UM 31 CHAPTER 3 3.5 INSTALLATION External Trigger To set an external trigger, connect the IE-789831-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-789831-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-789831-NS-EM1. Input a high-level pulse signal for 2 CPU operation clocks or more. 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 provided. (1) Signals input to or output from the emulation CPU (2) Signals input from the target system via a gate (3) LCD-related signals (4) Other signals The IE-789831-NS-EM1's circuit is used as follows for signals listed in (1) to (4) above. (1) Signals input to or output from the emulation CPU The following signals perform the same operations as in the PD789830 and the PD78F9831. However, a 1 pull-down resistor and 100 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 timing shows a delay compared to the PD789830 and the PD78F9831. Their AC characteristics and DC characteristics are therefore different from the PD789830 and the PD78F9831 making it necessary to observe a stricter timing design than in the PD789830 and the PD78F9831. * RESET signal * Signals related to clock input In all the signals input from the target system, the RESET signal and signals related to clock input are input to the emulation CPU via a logic IC. The DC characteristics are therefore different from the PD789830 and the PD78F9831. User's Manual U14202EJ2V0UM 33 CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICE AND TARGET INTERFACE CIRCUIT (3) LCD-related signals Because the following signals input/output LCD-related signals, special processing is not performed in the IE789831-NS-EM1. * Common pins (COM0 to COM15) * Segment pins (S0 to S31) * Port 5 (alternately functions as P50 to P57/S32 to S39) (4) Other signals * VDD pin When the emulation CPU is operating at 5 V, its power is supplied from the IE-789831-NS-EM1, but when operating at low voltage, its power is supplied from the low-voltage pin (TP1). The VDD pin of the target system is only used to control the LED (TVCC) in the IE-789831-NS-EM1 that monitors the input of the target system's power supply. * VSS pin The VSS pin is connected to GND in the IE-789831-NS-EM1 * TEST/VPP pin The TEST/VPP pin is not used in the IE-789831-NS-EM1. * X2, XT2 pins The X2 and XT2 pins are not used in the IE-789831-NS-EM1. 34 User's Manual U14202EJ2V0UM CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICE AND TARGET INTERFACE CIRCUIT Figure 4-1.
