Using IE-784937-NS-EM1 in combination with IE-78K4-NS: Short 1 and 2 (shipment setting) Using IE-784000-R in combination with IE-784937-NS-EM1 and IE-78K4-R-EX3: Short 2 and 3 3.3 Clock Settings 3.3.1 Overview of clock settings The main system clock to be used during debugging can be selected from (1) to (3) below, and the timer clock from (1) and (2) below. (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.

(2) Clock that is mounted by user The user is able to mount any clock supported by the set specifications on the IE-784937-NS-EM1. First mount the resonator on the parts board, then attach the parts board to the IE-784937-NS-EM1. This method is useful when using a different frequency from that of the pre-mounted clock.

Table 3-3. DIP Switch Setting for NMI Interrupt Mask Status DIP Switch Setting 1 (NMIMSK) No NMI mask (initial setting) ON NMI masked 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. 3.4.2 Wait (WAIT)/hold (HOLD) mask function By setting switches 2 to 4 of the DIP switch (SW1) in the IE-784937-NS-EM1, it is possible to mask the wait (WAIT) and hold (HOLD) alternate functions of the P66 pin in the µPD784938A Subseries. Table 3-4. DIP Switch Setting for Wait (WAIT)/Hold (HOLD) Mask Function Status DIP Switch Setting 2 (WAITMSK) 3 (HOLDMASK) 4 (P66ON) No mask (initial setting) OFF OFF ON Hold masked OFF ON OFF Wait masked ON OFF OFF Caution Do not set the DIP switch to settings other than those above. 3.4.3 Wait display function setting By setting switch 5 of the DIP switch (SW1) in the IE-784937-NS-EM1, it is possible to display the status of “waiting” with an LED light. Table 3-5. DIP Switch Setting for Wait Display Function Status DIP Switch Setting 5 (WAITLED) Wait (WAIT) status not displayed OFF Wait (WAIT) status displayed (initial setting) ON Caution When pin P66 is used as a port pin, unless the DIP switch is turned OFF the LED may light up. User’s Manual U16556EJ1V0UM 29 CHAPTER 3 INSTALLATION 3.4.4 Hold display function setting The IE-784937-NS-EM1 lights the LED during hold to indicate the status. The hold display function can be selected by setting 6 of the DIP switch (SW1). Table 3-6. DIP Switch Setting for Hold Display Function Status DIP Switch Setting 6 (HOLDLED) Hold (HOLD) status not displayed (initial setting) OFF Hold (HOLD) status displayed ON Caution When using the P66 pin as a port, set the DIP switch to OFF. Otherwise, the LED may be lit. 3.5 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-784937-NS-EM1. Set the target voltage between 2.7 and 5.5 V during 6.29 MHz operation and between 4.5 and 5.5 V during 12.58 MHz operation. • Maximum current consumption of TP1 30 5V 300 mA . . . . . . 2.7 V 250 mA User’s Manual U16556EJ1V0UM CHAPTER 3 INSTALLATION 3.6 External Trigger To set up an external trigger, connect it to the IE-784937-NS-EM1’s check pin, EXTOUT pin, and EXTIN pin as shown below.

Although the target device is a CMOS circuit, the IE-784937-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 µPD784938A Subseries. For the signals related to ports excluding port 7 (having alternate function as a pin for A/D converter), however, a 1 MΩ pull-down resistor and 22 Ω 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 7 (A/D converter input) • Signals related to port 9 • Signals related to port 10 • Signals related to PWM • Signals for ASTB/CLKOUT • Signals related to IEBus controller • Signals related to A/D converter • AVREF1 • AVSS • AVDD Note Note 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. 32 User’s Manual U16556EJ1V0UM CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS Figure 4-1.

Their AC characteristics and DC characteristics are therefore different from µPD784938A Subseries, making it necessary to observe a stricter timing design than in the case of µPD784938A 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. User’s Manual U16556EJ1V0UM 35 CHAPTER 5 RESTRICTIONS The IE-784937-NS-EM1 has the following restrictions. • The specification of the STOP mode of the watch timer function is different from that of the target device. When the count clock is selected as the main clock, the timer stops in the target device in STOP mode, however, the timer does not stop in the IE-784937-NS-EM1. 36 User’s Manual U16556EJ1V0UM CHAPTER 6 CAUTIONS When using the IE-784937-NS-EM1, observe the cautions below. • Set the IE-784937-NS-EM1 as follows when using it in combination with the IE-78K4-R-EX3 in the IE-784000-R. Note that the setting described in 3.1 Installation Procedure (2) of the IE-78K4-R-EX3 User’s Manual (U16346E) is not required. (1) Set JP3 with 2 and 3 shorted. (2) Mount a crystal oscillator in the UMCLK socket. A 12.580 MHz crystal oscillator is mounted at shipment. (3) Set SW1 as shown below.
