Capability Improvements⁽¹⁾
• The DFS macro is no • T_CONFIG requirement is removed
longer needed
• DCM_RESET requirement is removed
• DCM_INPUT_CLOCK_STOP requirement is
removed by a macro (automatically inserted by ISE
software)

Notes:
1. 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.
