Connection between IE-703002-MC and IE-703037-MC-EM1
The procedure for connecting the IE-703002-MC and IE-703037-MC-EM1 is described below.
Caution
Connect carefully so as not to break or bend connector pins.
<1> Remove the pod cover (upper and lower) of the IE-703002-MC.
<2> Set the PGA socket lever of the IE-703037-MC-EM1 to the OPEN position as shown in Figure 1-4 (b).
<3> Connect the IE-703037-MC-EM1 to the PGA socket at the back of the IE-703002-MC pod (refer to Figure 1-4
(c)). When connecting, position the IE-703002-MC and IE-703037-MC-EM1 so that they are horizontal.
<4> Set the PGA socket lever of the IE-703037-MC-EM1 to the CLOSE position as shown in Figure 1-4 (b).
<5> Set the IE-703002-MC pod jumpers (JP1 to JP4).
Open JP1 (Remove the jumper contact and attach the removed jumper contact to one of the jumper pins to
avoid losing it.)
Retain the factory settings of JP2 (pins 1 and 2 shorted, and pins 5 and 6 shorted).
Short pins 1 and 2 of JP3.
Retain the factory settings of JP4 (pins 2 and 3 shorted).
<6> Fix the IE-703037-MC-EM1 between the IE-703002-MC pod covers (upper and lower) with the plastic screws
(supplied with the IE-703002-MC).
<7> Fix the IE-703002-MC pod cover (upper) end with nylon rivets.
Remark
For the JP1 setting, refer to 2.3 Illegal Access Detection ROM Setting. For JP3 and JP4, refer
to 2.4 CPU Operation Voltage Range Switch Setting.

CAUTIONS
VDD, BVDD, and EVDD of Target System
(1) BVDD in the target system is not connected to BVDD in the evaluation chip in the IE-703002-MC.
The IE-703002-MC uses BVDD of the target system for the following purposes:
• Power ON/OFF detection of target system
• BVDD emulation of target system
(2) When the BVDD voltage of the target system is 1 V or higher, the evaluation chip in the emulator operates using
the supply of VDD and EVDD from the target system.
The power consumption is equivalent to that of the
V850/SB1.
(3) When the BVDD voltage of the target system is lower than 1 V, the emulator recognizes the target system power
is off and operates at VDD = BVDD = EVDD = 5.0 V.

CAUTIONS
NMI Signal
The input signal (NMI signal) from the target system is delayed (tpD = 0.25 ns (TYP.)) because it passes through
QS3125 (Q switch) 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 = ±0.5 µA (MAX.).

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.

MAM Register
Debugging of the MAM register cannot be performed in the emulator.
If debugging the MAM register with
software, proceed with care.
In the target device, ports can be used as address buses by setting values to the MAM register (address:
FFFFF068H), which is mapped in the internal peripheral I/O area, using software (separate bus function). In the
emulator, however, switching to the separate bus through a 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)

NMI Signal Mask Function
When using the P00/NMI pin in the port mode, do not mask the NMI signal.

Bus Interface Pin
The operation of the pin for the bus interface differs between the emulator and the target device as follows.
