CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS
This chapter describes the differences between the target device’s signal lines and the signal lines of the IE-
Although the target device is a CMOS circuit, the IE-789177-NS-EM1’s target interface circuit consists of
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 IE system’s circuit is used as follows for signals listed in (1) to (4) above.
The following signals perform the same operations as in the µ PD789167, 789177 Subseries. However, a 1 MΩ
pull-down resistor and 100 Ω resistor are inserted in series.
Since the following signals are input via a gate, their timing shows a delay compared to the µ PD789167, 789177
Subseries.
