APPENDIX A CHARACTERISTICS OF TARGET INTERFACE
The target interface (signals connecting the in-circuit emulator and target system) operate, in terms of function,
as if an actual device were connected. The characteristics, however, may be different from those of the actual
device. The target interface of the QB-V850ESFJ3 is one of the equivalent circuits shown below.
