The following table lists the names and positions of the SW1 and SW2
switches for configuring the XC4003E FPGA from the XChecker/
Parallel Cable III.
When you configure both the XC3020A and XC4003E devices using
the XChecker/Parallel Cable III, configure the XC4003E FPGA first. If
you configure the XC3020A first, its configuration is lost when the
XC4003E FPGA configures because the PROG signal connects
directly to the XC4003E PROG input and through a diode to the
XC3020A DONE/PROG input.
The following table lists the names and positions of the SW1 and SW2
switches for configuring the XC3020A FPGA from the serial PROM.
