begins on the rising edge of CS after a valid write sequence and ends when the internal self-timed write
cycle is complete.
3: This parameter is not tested but guaranteed by characterization. For endurance estimates in a specific appli-
cation, please consult the Total Endurance Model which can be obtained on our BBS or website.
