Test Conditions
Note 1: This parameter is periodically sampled and not 100% tested.
2: This parameter is not tested but ensured by characterization. For endurance estimates in a specific
application, please consult the Total Endurance Model which can be obtained from our web site:

3: T
WC begins on the rising edge of CS after a valid write sequence and ends when the internal write cycle
is complete.
