CHAPTER 5 DIFFERENCES BETWEEN TARGET DEVICE AND TARGET INTERFACE CIRCUIT

Differences between the signal lines of the target device and the signal lines of the IE-703079-MC-EM1 target

interface circuit are described in this chapter.

The target device is a CMOS circuit, whereas the target interface circuit of the IE-703079-MC-EM1 is configured

with an emulation circuit such as a gate array TTL or CMOS-IC.

When debugging the IE system connected to the target system, the IE system emulates as if the real target device

is operating on the target system.

Small differences occur however, because the IE system is emulating actual operation.

(1) Signals input/output to/from the emulation CPU

PD70F3079Y

(2) Other signals

The IE-703079-MC-EM1 circuit regarding the (1) and (2) signals described above is as follows.
