(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, the clock that is mounted on the emulation board installed in the IE-78K4-NS is used. 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-784976-NS-EM1. First mount the resonator on the parts board, then attach the parts board to the IE-784976-NS-EM1. This method is useful when using a different frequency from that of the pre-mounted clock.

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-784976-NS-EM1. Set the target voltage between 4.5 and 5.25 V. The maximum current consumption is 300 mA. 3.4 External Trigger To set an external trigger, connect the IE-784976-NS-EM1’s check pins EXTOUT and EXTIN as shown below. For pin characteristics, refer to the IE-78K4-NS User’s Manual (U13356E), and for usage methods, refer to the ID78K Series Ver.2.30 or Later Operation User’s Manual (Windows Based) (U15185E).

Although the target device is a CMOS circuit, the IE-784976-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 µPD784976 and 784976A Subseries. For the signals related to ports, excluding ports 0, 1, 7, 8, 9, and 10 (having alternate functions as pins for the A/D converter and FIP), however, a 1 MΩ pull-down resistor and 27 Ω resistor are inserted in series. • Signals related to port 0 (A/D converter input) • Signals related to port 1 (A/D converter input) • Signals related to port 2 • Signals related to port 4 • Signals related to port 6 • Signals related to port 7 (FIP output) • Signals related to port 8 (FIP output) • Signals related to port 9 (FIP output) • Signals related to port 10 (FIP output) • Signals related to A/D converter • AVSS • AVDD Note • Signals related to FIP 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.

Their AC characteristics and DC characteristics are therefore different from µPD784976 and 784976A Subseries, making it necessary to observe a stricter timing design than in the case of µPD784976 and 784976A Subseries. • Signals related to port 5 • 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. 30 User’s Manual U16376EJ1V0UM CHAPTER 5 RESTRICTIONS The IE-784976-NS-EM1 has the following restrictions. • SFR register CC (oscillation mode selection register) cannot be emulated. Preventive measures: Mode selection is possible by setting JP1 on the IE-784976-NS-EM1. • Mask option functions of ports 5, 7, 8, 9, and 10 are not supported.
