CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS

User’s Manual U13390EJ2V0UM

(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

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

PD789800

Subseries.

•

RESET signal

•

Signals related to clock input

(3) Other signals

•

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

) supplied from the voltage supply pin (TM1) when

connected to the target system.

The V

pin of the target system is used only for control of LED1 (USER V

), which indicates whether the

target system’s power is on or off.

•

The V

pin is internally connected to GND in the IE-789801-NS-EM1.

•

/IC pins

These are not used for the IE-789801-NS-EM1

•

X2 pin

This is not used for the IE-789801-NS-EM1.
