(1) Clock that is already mounted on emulation board (2) Clock that is mounted by user (3) External clock If the target system includes an internal clock, select either "(1) Clock that is already mounted on emulation board" or "(2) Clock that is mounted by user". For an internal clock, the target device is connected to a resonator 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 resonator that is mounted on the target system is not used. Instead, it uses the clock that is mounted on the emulation board, which is installed for the IE-78K4-NS. If the target system includes an external clock, select "(3) External clock". For an 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 3-2. Figure 3-2.

Its frequency is 12.58 MHz. Figure 3-3.

(2) Clock that is mounted by user The user is able to mount any clock supported by the set specifications on the IE-784908-NS-EM1. First mount the resonator on the parts board, then attach the parts board to the IE-784908-NS-EM1. This method is useful when using a different frequency from that of the pre-mounted clock.

Remark The IE-784908-NS-EM1's factory settings 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-784908-NS-EM1 is shipped, a 12.58-MHz crystal oscillator is already mounted in the IE-784908NS-EM1's UMCLK socket. When using the factory-set mode settings, there is no need to make any other hardware settings. When starting the integrated debugger (ID78K4-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).

There is no need to make any settings via the integrated debugger (ID78K4-NS). 32 User's Manual U13743EJ1V0UM00 CHAPTER 3 INSTALLATION 3.3 Pin Mask Function Settings 3.3.1 Wait (WAIT) mask function By setting the DIP switch (SW1) in the IE-784908-NS-EM1, it is possible to mask the alternate function (WAIT) and HOLD of pin P66 in the PD784908 Subseries. Table 3-3. DIP Switch Setting for Wait (WAIT) Mask Function Status DIP Switch Setting 2 (WAITMSK) 3 (HOLDMSK) 4 (P66ON) No mask (initial setting) OFF OFF ON Hold mask status OFF ON OFF Wait mask status ON OFF OFF Caution Do not set the DIP switch to settings other than those above. 3.3.2 Wait display function setting By setting the DIP switch (SW1) in the IE-784908-NS-EM1, it is possible to display the statuses of "waiting" and "holding" with an LED light. Table 3-4. DIP Switch Setting for Wait Display Function Status DIP Switch Setting 5 (HOLDLED) 6 (WAITLED) HOLD status is displayed, WAIT status is not displayed (initial setting) ON OFF HOLD status is not displayed, WAIT status is displayed OFF ON Caution When pin P66 is used as a port pin, unless the DIP switch is turned OFF the LED may light up. 3.3.3 NMI interrupt mask setting By setting switch 1 of the DIP switch (SW1) in the IE-784908-NS-EM1, it is possible to mask the NMI interrupt, which is the alternate function of the port 20. Table 3-5. DIP Switch Setting for NMI Interrupt Mask Status DIP Switch Setting 1 (NMIMSK) No NMI mask (initial setting) ON NMI mask status OFF Caution Because the NMI interrupt is the alternate function of the P20 pin, this pin cannot operate as the P20 pin when the NMI mask status has been set. User's Manual U13743EJ1V0UM00 33 CHAPTER 3 INSTALLATION 3.4 Low-Voltage Emulation Setting Low-voltage emulation is possible in the IE system. When the target system is operating on low voltage, supply the same voltage as the target system to the TP1 terminal pin of the IE-784908-NS-EM1 (this is unnecessary when the TP1 is 5 V). Set the target voltage between 3 and 5 V. * Maximum current consumption of TP1 34 5V 300 mA . . . . . . 3V 250 mA User's Manual U13743EJ1V0UM00 CHAPTER 3 INSTALLATION 3.5 External Trigger To set up an external trigger, connect it to the IE-784908-NS-EM1's check pin, EXTOUT pin, and EXTIN pin as shown below. See the integrated debugger (ID-78K4-NS) User's Manual (U12796E) for descriptions of related use methods and pin characteristics. Figure 3-12.

Although the target device is a CMOS circuit, the IE-784908-NS-EM1's target interface circuit consists of an emulation CPU, TTL, CMOS-IC, and other emulation circuits. 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 directly input/output to/from the emulation CPU (2) Signals input from the target system via a gate (3) Other signals The IE system's circuit is used as follows for signals listed in (1) to (3) above. (1) Signals directly input/output to/from the emulation CPU The following signals perform the same operations as in the PD784908 Subseries. For the signals related to ports excluding port 7 (having alternate functions as pins for A/D converter), however, a 1-M pull-down resistor and 22- 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 * Signals related to port 5 * Signals related to port 6 * Signals related to port 7 (A/D converter input) * Signals related to port 9 * Signals related to port 10 * Signals related to A/D converter * AVREF * AVSS * Signals related to PWM * ASTB/CLKOUT TM * IEBus interface signal TX, RX Remark The AVDD pin on the target system is not connected to the IE system. Either the power supply of the IE system or the power supply supplied to TP1 is supplied to the AVDD pin of the emulation CPU.

Their AC characteristics and DC characteristics are therefore different from PD784908 Subseries, making it necessary to observe a stricter timing design than in the case of PD784908 Subseries. * RESET signal * Signals related to clock input Figure 4-2.

The VDD pin of the target system is only used to control the LED (USERVDD) in the IE system that monitors the input of the target system's power supply. * VSS pin The VSS pin is connected to GND inside the IE system. 40 User's Manual U13743EJ1V0UM00 APPENDIX EMULATION PROBE PIN ASSIGNMENT TABLE Table A-1.
