Table 2-3. JP1 setting in IE-703002-MC JP1 Description Note Open Illegal Access Detection ROM (mounted on IE-703017-MC-EM1) for V850/SA1 is used. Note When JP1 is set open, keep the removed jumper contact attached to one pin JP1 as shown in the drawing at right. Jumper contact 2.4 CPU Operation Voltage Range Switching Setting If using the IE-703002-MC for an in-circuit emulator for V850/SA1 by connecting IE-703017-MC-EM1, set JP3 and JP4 of the IE-703002-MC as follows. Table 2-4. JP3 and JP4 Setting in IE-703002-MC JP3, JP4 Description JP3 Operating voltage range of IE-703002-MC is from 2 to 3.6 V. 1 2 (Open) JP4 1 Operating voltage range of target system is from 2 to 4.5 V. (Since operating voltage of V850/SA1 is from 2 to 3.6 V, this setting is effective) 2 3 Caution With the setting of JP3 and JP4, the IE-703002-MC operates in the same voltage as the target system if the target system power is ON. If the target system power is OFF or the emulator is used as a stand-alone unit, the IE-703002-MC always operates in 3.3 V. 23 CHAPTER 2 2.5 NAME AND FUNCTION OF COMPONENTS Separate Bus Function Setting To use the separate bus function, J1 of IE-703017-MC-EM1 must be set. Table 2-5 shows the correspondence between the MAM register and J1 settings. Table 2-5.

The IE-703002-MC uses the BVDD of the target system for the following purposes: • Power ON/OFF detection of target system • BVDD emulation of target system (2) When the voltage of the target system is 1 V or higher, the evaluation chip in the emulator is supplied VDD to operate by the target system. The power consumption is equivalent to that of the µPD70F3017. (3) When the voltage of the target system is lower than 1 V, the emulator recognizes the target system power is off and operates at 3.3 V. Figure 4-1. Schematic Diagram of Power Supply Acquisition Target system IE-703017-MC-EM1 IE-703002-MC BVDD Target voltage emulation V850/SA1 I/O chip BVDD VDD Relay BVDD >= 1 V Evaluation chip BVDD < 1 V 27 CHAPTER 4 4.2 CAUTIONS NMI Signal The input signal (NMI signal) from the target system is delayed (tpD = 10 ns (MAX.)) because it passes through FPGA before it is input to the I/O chip of the emulator. In addition, the DC characteristics change. The input voltage becomes VIH = 2.0 V (MIN.) and VIL = 0.8 V (MAX.). The input current becomes IIN = ±1.0 µA (MAX.). Figure 4-2. NMI Signal Flow Path IE-703017-MC-EM1 Target system NMI signal NMI pin 4.3 FPGA I/O chip VPP Signal The VPP signal from the target system is connected to LED via a 330-Ω resistor in the emulator. It is not connected to the evaluation chip in the emulator. Figure 4-3. VPP Signal Flow Path IE-703017-MC-EM1 Target system VPP signal 330 Ω 4.4 LED Evaluation chip MAM Register Debugging of MAM register cannot be performed in the emulator. If debugging MAM register with software, proceed with care. In the target device, the port can be used as an address bus by setting a value to the MAM register (address: FFFFF068H) that is mapped in the internal peripheral I/O area with the software (Separate bus function). In the emulator, however, switching to the separate bus through MAM register setting by software is impossible. To use the separate bus function, set the J1 jumper in advance. (refer to 2.5 Separate Bus Function Setting) 28 CHAPTER 4 4.5 CAUTIONS NMI Signal Mask Function When using the P00/NMI pin in the port mode, do not mask the NMI signal. 4.6 Bus Interface Pin The operation of the pin for the bus interface differs between the emulator and the target device as follows.
