Note:
(1) This parameter is tested initially and after a design or process change that affects the parameter.
(2) A write pulse of less than 20ns duration will not initiate a write cycle.
(3) A timer of duration tBLC max. begins with every LOW to HIGH transition of WE. If allowed to time out, a page or byte write will begin;
however a transition from HIGH to LOW within tBLC max. stops the timer.
