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-780338-

NS-EM1’s target interface circuit.

Although the target device is a CMOS circuit, the IE-780338-NS-EM1’s target interface circuit consists of

emulation circuits such as an emulation CPU, TTL, and CMOS-IC.

When the IE system is connected with the target system for debugging, the IE system performs emulation so as to

operate as the actual target device would operate in the target system.

However, some minor differences exist since the operations are performed via the IE system’s emulation.

(1) Signals input or output from the emulation CPU (

PD780009A)

(2) Signals input or output from the emulation CPU (

PD78F0338)

(3) Other signals

The IE-780338-NS-EM1’s circuit is used as follows for signals listed in (1) to (3) above.

(1) Signals input or output from the emulation CPU (

The same applies to the connection of alternate-function pins as no circuits exist in the IE

system.
