See LX and SX Errata for details on LX and SX Step 1 and ES silicon.
Speed Specification v1.65 or later must be used for XC4VFX40 devices (all speed grades) and for XC4VFX100 (-12 speed grade only). In this case,
these family members (and speed grades) are released to production before a speed specification is released with the correct label (Advance,
Preliminary, or Production). These labeling discrepancies will be corrected in a subsequent speed specification release.
