25.4.2.19 Enable EEPROM Emulation Command
The Enable EEPROM Emulation command causes the Memory Controller to enable EEE activity. EEE
activity is disabled after any reset.
Upon clearing CCIF to launch the Enable EEPROM Emulation command, the CCIF flag will set after the
Memory Controller enables EEE operations using the contents of the EEE tag RAM and tag counter. The
Full Partition D-Flash or the Partition D-Flash command must be run prior to launching the Enable
EEPROM Emulation command.
