Terminology
Term Emulation device
The meanings of certain terms used in this manual are listed below.
Meaning This is a general term that refers to the device in the emulator that is used to emulate the target device. It includes the emulation CPU. This is the CPU block in the emulator that is used to execute user-generated programs. This is the device (a real chip) that is the target for emulation. The device that is targeted for debugging. This includes the target program and the hardware provided by the user. When defined narrowly, it includes only the hardware. This refers to the combination of the IE-78K4-NS and the IE-784928-NS-EM1.

The IE-784928-NS-EM1 includes the 4915NS CHIPSET and the 4928 CHIPSET. (1) When the 4915NS CHIPSET is used to emulate the PD784915 Subseries, use the 4928 CHIPSET to emulate the PD784928 and 784928Y Subseries. (2) When using an emulation probe, connect the 4915NS CHIPSET or the 4928 CHIPSET to the probe tip. (3) When not using an emulation probe, connect the 4915NS CHIPSET or the 4928 CHIPSET to the L1 and L2 connectors on the IE-784928-NS-EM1. Caution Do not connect the chipset boards to both the emulation probe tip and the L1 and L2 connectors on the IE-784928-NS-EM1 at the same time.

Caution Do not connect the chipset board while the emulation probe is in use. (2) Connection with IE-78K4-NS main unit See the IE-78K4-NS User's Manual (U13356E) for a description of how to connect the IE-784928-NS-EM1 to the IE-78K4-NS. (3) Connection with emulation probe See CHAPTER 4 EMULATION PROBE (EP-784928GF-NS) for a description of how to connect an emulation probe to the IE-784928-NS-EM1. On this board, connect the emulation probe to CN1. Caution A clock cannot be supplied to the emulation device from the oscillation clock in the target system. When operating at a frequency other than 16 MHz, attach a clock device of the same oscillation frequency as that supplied to the target device to X1.

Target Device Setting
When emulating the PD784915 Subseries, connect the 4915NS CHIPSET to L1 and L2. When emulating the PD784928 and PD784928Y Subseries, connect the 4928 CHIPSET to L1 and L2.

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. (1) Clock that is already mounted on emulation board (2) Clock that is mounted by user (3) External clock Caution Use "clock that is already mounted on emulation board" for the subsystem 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, which is installed for 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. External Circuits Used as System Clock Oscillator (a) Internal clock

(2) Clock that is mounted by user The user is able to mount any clock supported by the set specifications on the IE-784928-NS-EM1. First mount the resonator on the parts board, then attach the parts board to the IE-784928-NS-EM1. This method is useful when using a different frequency from that of the pre-mounted clock.

Caution
When using an external clock, open the configuration dialog box when starting the integrated debugger (ID78K4-NS) and select "External" in the area (Clock) for selecting the CPU's clock source (this selects the user's clock).
Remark The IE-784928-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-784928-NS-EM1 is shipped, a 16-MHz crystal oscillator is already mounted in the IE-784928-NSEM1's X1 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).

Pin Mask Function Settings
* NMI interrupt mask setting By setting a switch (SW1) on the 4915NS CHIPSET, or 4928 CHIPSET in the IE-784928-NS-EM1, it is possible to mask the NMI interrupt, which is the alternate function of the P20 pin. Table 3-2. Slide Switch Setting for NMI Interrupt Mask Function
Status Slide Switch Setting SW1 No NMI mask (initial setting) NMI masked OFF ON
Caution
Because the NMI interrupt is the alternate function of the P02/INTP2 pin, this pin cannot operate as the P02/INTP2 pin when the NMI mask status has been set.

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-784928-NS-EM1 (this is unnecessary when TP1 is 5 V). Set the target voltage between 2.7 and 5 V. * Maximum current consumption of TP1 5V

CHAPTER 4 EMULATION PROBE (EP-784928GF-NS)
When using the IE-784928-NS-EM1 connected to the target system, a dedicated emulation probe (EP-784928GFNS: sold separately) is needed. Using the EP-784928GF-NS for connection enables debugging of the hardware and software of the target system in which the PD784915, PD784928, or PD784928Y Subseries are employed. For connection details, refer to 4.2 Connection Procedure.
4.1
Configuration of EP-784928GF-NS
The configuration of the EP-784928GF-NS is described below.

CHAPTER 5 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS
This chapter describes differences between the target device's signal lines and the signal lines of the IE-784928NS-EM1's target interface circuit. Although the target device is a CMOS circuit, the IE-784928-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 PD784915, 784928 Subseries. For the signals related to ports 0, 4, and 5, a 22- resistor is inserted in series. The NMI performs mask control by means of SW1 on the chipset board. * Signals related to port 0 * 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 8 * Signals related to port 9 * Signals related to external input (INTP0 to INTP2) * Signals related to timer output (PT00 to PT02) * Signals related to serial communication (SCK2, SO2, SI2/BUSY) * Signals related to A/D converter (ANI08 to ANI11) * NMI

CHAPTER 5 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS
(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 that of the
PD784915, 784928 Subseries. Their AC characteristics and DC characteristics are therefore different from the PD784928 Subseries, making it necessary to observe a stricter timing design than in the case of the PD784915, 784928 Subseries.

(3) Other signals * VDD pin When the emulation CPU is operating at 5 V, its power is supplied from the internal IE system, 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 (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.
