Notes:
1.
IFF = Input Flip-Flop or Latch
2.
Setup time is measured relative to the Global Clock input signal with the fastest route and the lightest load. Hold time is measured
relative to the Global Clock input signal with the slowest route and heaviest load.
3.
A Zero “0” Hold Time listing indicates no hold time or a negative hold time. Negative values can not be guaranteed “best-case”, but
if a “0” is listed, there is no positive hold time.
