Notes:
1. The OE input signal must be a minimum of 3 clock periods with width.
2. The internal enable is asserted and de-asserted on the falling edge of clock.
3. The internal enable occurs 2.5 clock cycles (plus the set-up time of OE with the rising edge of clock) after the rising edge of the external OE.
4. If OE does not meet the t
