begins on the rising edge of CS after a valid write sequence and ends when the internal write cycle is
complete.
3: 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 Microchip’s web site
