Appendix A Target Interface Characteristics - NEC IE-703217-G1-EM1 User Manual

APPENDIX A TARGET INTERFACE CHARACTERISTICS

From a functional aspect, the target interface (signals that connect the in-circuit emulator and target system)
appears to operate as if an actual device were connected, but there may be differences with the actual device from a
performance aspect. The target interface of this product can be any one of the interfaces described in Figures A-1 to
A-10. The processing of the target interface for each target device is described in Tables A-1 to A-3.
