CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS
This chapter describes differences between the target device’s signal lines and the signal lines of the IE-780988-
Although the target device is a CMOS circuit, the IE-780988-NS-EM4’s target interface circuit consists of emulation
When the IE system is connected with the target system for debugging, the IE system performs emulation so as to
However, some minor differences exist since the operations are performed via the IE system’s emulation.
The circuit of the IE system is used as follows for signals listed in (1) to (3) above.
