25.4.2.20 Disable EEPROM Emulation Command
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.
25.4.2.21 EEPROM Emulation Query Command
The EEPROM Emulation Query command returns EEE partition and status variables.
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
values are returned: DFPART = 0x_FFFF, ERPART = 0x_FFFF, ECOUNT = 0x_FFFF, Dead Sector
Count = 0x_00, Ready Sector Count = 0x_00.
