CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS
This chapter describes the differences in electrical specifications between the target device and the target
Unlike the target device, the target interface circuit of the IE system comprises emulation circuits such as the
The IE system’s circuit is used as follows for signals listed in (1) to (3) above.
The following signals perform the same operations as in the µ PD789046 Subseries. However, a 1 MΩ pull-down
Since the following signals are input via a gate, their signals show a delay compared to the µ PD789046 Subseries.
When debugging the µ PD789046 Subseries, connect the target system to IE-789046-NS-EM1 via the emulation
