Input pad setup and hold times are specified with respect to the internal clock (IK). For setup and hold times with respect to the clock
input pin, see the pin-to-pin parameters in the Guaranteed Input and Output Parameters table.
Voltage levels of unused pads, bonded or unbonded, must be valid logic levels. Each can be configured with the internal pull-up
(default) or pull-down resistor, or configured as a driven output, or can be driven from an external source.
Timing is based on the XC4005E. For other devices see the XACT timing calculator.
