Notes:
1.
Maximum frequency and setup/hold timing parameters are for 3.3V and 2.5V configuration voltages.
2.
To support longer delays in configuration, use the design solutions described in UG190: Virtex-5 FPGA User Guide. 3.
DO will hold until next DRP operation.
4.
Only during configuration, the last edge is determined by a weak pull-up/pull-down resistor in the I/O.
