3 Flex I/O Interface Pins as High Speed Signals (Clock Inputs) using Clock Devices

Flex I/O Interface Pins as High Speed Signals (Clock Inputs) Using Clock Devices

Thus, whenever Flex I/O pins are used as high speed clock pins, if a user inserts an incompatible card which has side band signals defined other than clock signals. This poses a leakage risk or device reliability issue until the interface engagement determines the card is not compatible.
