Mode Switch Settings

This section describes the SW1 and SW2 switch settings for configuring the XC3020A and XC4003E devices.

The following table lists the names and positions of the SW1 and SW2 switches for configuring the XC3020A FPGA from the XChecker or 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.
