UCF Location Constraints
Figure 15-7 provides the UCF constraints for the FX2 connector, including the I/O pin
assignment and the I/O standard used, assuming that all connections use single-ended
I/O standards. These header connections are shared with the 6-pin accessory headers, as
shown in Figure 15-11, page 124.
