CHAPTER 4 PG-FP4 OPERATION USING GUI SOFTWARE
Figure 4-29. Setup Window – Supply Voltage
[Vdd [V]]
Displays the default Vdd level set by the parameter file in volts (V).
This Vdd level can be changed by input.
[Vdd2 [V]]
Displays the default Vdd2 level set by the parameter file in volts (V).
If the specifications of the target device require two types of Vdd for writing the flash memory, Vdd2 specifies
a low-level signal voltage. This voltage level can also be changed by input.
[On Target check box]
Check On Target if the VDD/VDD2 voltages are supplied from the target system.
The power supply detection function of the VDD pin differs depending on the setting of the On Target check
box.
• When VDD is set to be supplied from FP4 (On Target not checked)
If Target VDD reaches 0.2 V before VDD is supplied, the error message “Target power detected! Check
Setup” is displayed in the communication Log window.
• When VDD is set to be supplied from the target (On Target checked)
If VDD is outside the range of ±5% of the VDD set value just before communication starts, the error message
“No VDD applied or Voltage is out of range” is displayed in the communication log window.
Caution
Set the values of the VDD/VDD2 voltages supplied by the target system as Vdd [V] and Vdd2
[V] before checking On Target. The target system may be damaged if proper values are not
set.
