Notes:
11. X = 69 for the x36 configuration. X = 50 for the x18 configuration.
12. All Voltage referenced to VSS (GND).
13. Overshoot: VIH(AC)<VCC+1.5V for t<tKHKH/2, Undershoot: VIL(AC)<–0.5V for t<tKHKH/2, Power-up: VIH<3.6V and VCC<3.135V and VCCQ<1.4V for t<200 ms.
During normal operation, VCCQ must not exceed VCC. Control input signals (such as R/W, ADV/LD, etc.) may not have pulse widths less than tKHKL (min.).
14. This parameter is sampled.
