26.4.2.20 Disable EEPROM Emulation Command
Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not
available from Freescale for import or sale in the United States prior to September 2010: S12XE products in 208 MAPBGA packages
The Disable EEPROM Emulation command causes the Memory Controller to suspend current EEE
activity.

Upon clearing CCIF to launch the Disable EEPROM Emulation command, the Memory Controller will
halt EEE operations at the next convenient point without clearing the EEE tag RAM or tag counter before
setting the CCIF flag.

Upon clearing CCIF to launch the EEPROM Emulation Query command, the CCIF flag will set after the
EEE partition and status variables are stored in the FCCOBIX register.If the Emulation Query command
is executed prior to partitioning (Partition D-Flash Command
Section 26.4.2.15),
the following reset
values are returned: DFPART = 0x_FFFF, ERPART = 0x_FFFF, ECOUNT = 0x_FFFF, Dead Sector
Count = 0x_00, Ready Sector Count = 0x_00.
