<1> Supply voltage
The supply voltage section allows you to specify the voltage levels for target device programming. Depending
on the target device type, one (V
DD
) or two (V
DD
and V
DD2
) voltage levels need to be specified.
In general, V

voltages that are supplied when the target device is programmed should be supplied by
the target system. Although they can be supplied by the PG-FP4, the current flow is not large enough to
operate the whole target system (maximum of 200 mA). Therefore, supply voltage via the PG-FP4 only when
a dedicated writing adapter such as an FA adapter is used.
