, 18:37, 24 June 2008→Configuration Pins: added SPI variant select pins
=== Configuration Pins ===
=== Configuration Pins ===
These pins are used for the programming of the FPGA.
These pins are used for the programming of the FPGA. Many of these pins revert to user I/O pins after programming is complete.
