Figure 4-24. Setup Window – Supply Oscillator
[On Target check box]
Specifies whether the clock signal is supplied from the PG-FP4 or target device.
If this is checked, the clock of the target system is used.
If it is not checked, the clock of the PG-FP4 is supplied to the target.
[Frequency list box]
Sets the oscillation frequency for signal generation.
When using the clock of the target system (when the On Target check box is checked), input the frequency to
be used.
When using the clock of the PG-FP4 (when the On Target check box is not checked), select a frequency from
the following:
•
1 MHz
•
2 MHz
•
4 MHz
•
5 MHz
•
6 MHz
•
8 MHz
•
10 MHz
•
12 MHz
•
16 MHz
•
20 MHz
Note that the frequency range in which a device can operate differs depending on the device. Check the
specifications of the device before setting the frequency.
[Multiply rate]
Specifies the division rate or multiplication rate of the target device.
If the target device has a PLL circuit, select the PLL mode and enter a division rate or multiplication rate in
accordance with the environment used.
The selectable division rate or multiplication rate differs depending on the device. Confirm the specifications
of the device before setting them.
If the target device does not have a PLL circuit, select the Internal/Direct mode.
In the initial screen, the default settings set by the parameter file are displayed.
