2.3 Illegal Access Detection ROM Setting
If using the IE-703002-MC for an in-circuit emulator for the V850/SV1 by connecting the IE-703040-MC-EM1, set
JP1 of the IE-703002-MC as follows.
Table 2-3. JP1 Setting in IE-703002-MC
JP1 Description
Open Note Illegal access detection ROM (mounted on IE-703040-MC-EM1) for V850/SV1 is
used.
Note When JP1 is set open, keep the removed jumper contact attached to one pin
as shown in the drawing on the right.

2.4 CPU Operation Voltage Range Switching Setting
If using the IE-703002-MC for an in-circuit emulator for the V850/SV1 by connecting the IE-703040-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
(Open)
1
2
The operation voltage range of the IE-703002-MC is to 2 to 3.6 V
JP4
1
2
3
The operation voltage range of the target system is 2 to 4.5 V.
(Use this setting since the operation voltage range of the V850/SV1 is 2 to 3.6 V.)
Caution By settings of JP3, JP4 above, when the power supply of the target system is on, the IE-703002-
MC operates at the same voltage as the target system.
The IE-703002-MC always operates at 3.3 V when the power supply of the target system is off and
using emulator as standalone unit.
