Appendix A Electrical Characteristics
A.3.1.24
The typical EEE copy down time is given by the following equation
The maximum EEE copy down time is given by the following equation
Worst case for Enable EEPROM Emulation allows for all the EEE records to have to be copied which is a
very low probability scenario only likely in the case that the EEE is mostly full of unchanging data (the
records for which are stored in consecutive D-Flash sectors).
