CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICE AND TARGET INTERFACE CIRCUIT
This chapter describes differences between the target device’s signal lines and the signal lines of the target
interface circuit of the IE system.
The target interface circuit of the IE system realizes emulation via an emulation circuit configured by an emulation
CPU, TTL, CMOS-IC, and other components. The electrical characteristics are different from those of the target
device because a protector and other circuits are provided.
(1) Signals directly input to or output from the emulation CPU
(2) Signals input from the target system via a gate
(3) Other
signals
The circuits of the IE-789860-NS-EM1 are used as follows for signals listed in (1) to (3) above. The same applies
to handling alternate-function pins, for which no circuit is provided in the IE system.
