CHAPTER 1 GENERAL

The IE-784000-R In-Circuit Emulator is a development tool that efficiently debugs the hardware and software of

an application system using NEC’s 78K/IV series microcomputer.

This in-circuit emulator is used in combination with the optional emulation board (IE-784000-R-EM), I/O emulation

board (IE-784026-R-EM1, etc.), and emulation probe (EP-78230GC-R, etc.).

The in-circuit emulator is connected to a host machine with an optional interface board (IE-70000-98-IF-B, IE-

70000-98N-IF, IE-70000-PC-IF-B, or IE-78000-R-SV3).
