Notes:
1. Rise/fall time ≤10 ns.
2. Card Enable Controlled Programming:
Flash Programming is controlled by the valid combination of the Card Enable (CE1#, CE2#) and Write Enable (WE#) signals.
For systems that use the Card Enable signal(s) to define the write pulse width, all setup, hold, and inactive write enable timing
should be measured relative to the Card Enable signal(s).
