AC test load = 50 pF for XCF01S/XCF02S/XCF04S; 30 pF for XCF08P/XCF16P/XCF32P.
Float delays are measured with 5 pF AC loads. Transition is measured at ±200 mV from steady-state active levels.
All AC parameters are measured with V

If T
This is the minimum possible T
3.3V, if FPGA data setup time = 15 ns, then the actual T
Guaranteed by design; not tested.
CF, EN_EXT_SEL, REV_SEL[1:0], and BUSY are inputs for the XCFxxP PROM only.
When JTAG CONFIG command is issued, PROM will drive CF Low for at least the T
