Notes:
1. Setup and Hold times are measured over worst case conditions (process, voltage, temperature). Setup time is measured relative to the
Global Clock input signal using the slowest process, highest temperature, and lowest voltage. Hold time is measured relative to the Global
Clock input signal using the fastest process, lowest temperature, and highest voltage.
2. IFF = Input Flip-Flop or Latch
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.
