Appendix A Electrical Characteristics
The standard shipping condition for both the D-Flash and P-Flash memory is erased with security disabled.
However it is recommended that each block or sector is erased before factory programming to ensure that
the full data retention capability is achieved. Data retention time is measured from the last erase operation.
