Clock Circuits
13
When using Flash Pro, use the STAPL(.STP) file to program the device.
Silicon Sculptor II requires the ISP programming adapter module SMPA-ISP-
ACTEL-2-KIT, then you can use either the bitstream (.BIT) file or STAPL
(.STP) file.
Clock Circuits
The evaluation board has two clock circuits, the 40MHz oscillator and the
manual clock.
40MHz
Oscillator
The 40MHz oscillator on the board is connected to JP4. JP4 connects
the clock to pin 24 of the devices. Pin 24 is a global input pin.
To use pin 24 for a different clock signal, disconnect JP4.
If you want to use a different Clock Frequency, purchase the Crystal from
Epson programmed to a variety of frequencies. The SG-8002JC40.000M-PCC
from Epson is also available through Digikey.
Manual Clock
When activated, the manual clock button (PB1) lights DS10 the pulse generated
LED and generates a pulse. This is connected to JP17. JP17 connects to pin
128 of the device. Pin 128 is a global input pin.
If you want to use pin 128 for a different clock signal, disconnect JP17.
LED Device Connections
Eight LED are connected to the device via jumpers. If the jumpers are in place,
the device I/O can drive the LED. The LED changes based on the following
output:
• A 1 on the output of the device lights the LED.
• A 0 on the output of the device switches off the LED.
• An unprogrammed or tristated output may show a faintly lit LED
Table 3-1 lists the LED/device connections.
