Illegal Access Detection ROM Setting
If using the IE-703002-MC for an in-circuit emulator for V850/SA1 by connecting IE-703017-MC-EM1, set JP1 of
the IE-703002-MC as follows.

Description
Open
Note
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
as shown in the drawing at right.

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
1
2
(Open)
Operating voltage range of IE-703002-MC is from 2 to 3.6 V.
JP4
1
2
3
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)
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.
