CHAPTER 4
(1) Signals input to or output from the EVA chip and the peripheral EVA chip
The following signals perform the same operations as in the µ PD789800 Subseries.
• Signals related to port 0
• Signals related to port 1
• Signals related to port 2
• Signals related to port 4
• Signals related to USB
(2) Signals input from the target system via a gate
Since the following signals are input via a gate, their timing shows a delay compared to the µ PD789800
Subseries.
• RESET signal
• Signals related to clock input
(3) Other signals
• V
pin
DD
The emulation CPU operates with the internal power supply of the IE system (5 V) when not connected to the
target system, and operates with the voltage (LV
connected to the target system.
The V pin of the target system is used only for control of LED1 (USER V
