CHAPTER 4 CAUTIONS
The following must be observed when using the IE-703204-G1-EM1.
4.1
Connection with Target System
Turn off power to the IE-V850ES-G1 before connecting the IE-703204-G1-EM1 to the target system.
4.2
Characteristics of Target Interface
The target interface (signals connecting the in-circuit emulator and the target system) functionally operates as if an
actual device is connected, however, the characteristics may be different than those of the actual device. The target
interface of the IE-703204-G1-EM1 is one of those shown in Figures 4-1 to 4-12. The target interface processing of
each target device is shown in Tables 4-1 and 4-2.
