(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 32 MHz. Figure 3-3. When Using Clock That Is Already Mounted on Emulation Board IE-78K4-NS IE-784046-NS-EM1 Target system Mounted oscillator (to be used) Emulation probe Resonator (not used) Remark The clock that is supplied by the IE-784046-NS-EM1's oscillator (encircled in the figure) is used. (2) Clock that is mounted by user The user is able to mount any clock supported by the set specifications on the IE-784046-NS-EM1. First mount the resonator on the parts board, then attach the parts board to the IE-784046-NS-EM1. This method is useful when using a different frequency from that of the pre-mounted clock.

Figure 3-5.

Remark The IE-784046-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-784046-NS-EM1 is shipped, a 32-MHz crystal oscillator is already mounted in the IE-784046-NSEM1'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). User's Manual U13744EJ1V0UM00 23 CHAPTER 3 INSTALLATION (2) When using clock mounted by user The settings described under either (a) or (b) are required, depending on the type of clock to be used. 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).

User's Manual U13744EJ1V0UM00 27 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-784046-NS-EM1, it is possible to mask the alternate function (WAIT) of pin P94 in the PD784046 Subseries, and the PD784054. Table 3-2. DIP Switch Setting for Wait (WAIT) Mask Function Status DIP Switch Setting 1 (WAITMSK) No mask (initial setting) Wait masked OFF ON 2 (P94ON) ON 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-784046-NS-EM1, it is possible to display the status of "waiting" with an LED light. Table 3-3. DIP Switch Setting for Wait Display Function Status DIP Switch Setting 3 (WAITLED) Wait (WAIT) status not displayed (initial setting) Wait (WAIT) status displayed OFF ON Caution When pin P94 is used as a port pin, unless the DIP switch is turned OFF the LED may light up. 3.3.3 NMI interrupt mask function By setting the DIP switch (SW1) in the IE-784046-NS-EM1, it is possible to mask the NMI interrupt, which is the alternate function of the P20 pin. Table 3-4. DIP Switch Setting for NMI Interrupt Mask Function Status DIP Switch Setting 1 (NMIMSK) No NMI mask (initial setting) NMI masked ON 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. 28 User's Manual U13744EJ1V0UM00 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-784046-NS-EM1. Set the target voltage between 4 and 5 V. * Maximum current consumption of TP1 5V . . . 300 mA . . . 4V 200 mA User's Manual U13744EJ1V0UM00 29 CHAPTER 3 INSTALLATION 3.5 External Trigger To set up an external trigger, connect EXTOUT pin to the IE-784046-NS-EM1's check pin TP2, and EXTIN pin to TP3 as shown below. See the integrated debugger (ID-78K4-NS) User's Manual (U12796E) for descriptions of related use methods. Figure 3-9.

Although the target device is a CMOS circuit, the IE-784046-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 PD784046 Subseries and the PD784054. For the signals related to ports excluding ports 7 and 8 (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 to 9 * CLKOUT signal * Signals related to A/D converter * AVREF * AVSS Caution 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 PD784046 Subseries and the PD784054, making it necessary to observe a stricter timing design than in the case of PD784046 Subseries and the PD784054. * RESET signal * Signals related to clock input Figure 4-2.
