Upon clearing CCIF to launch the Program D-Flash command, the user-supplied words will be transferred
to the Memory Controller and be programmed if the area is unprotected. The CCOBIX index value at
Program D-Flash command launch determines how many words will be programmed in the D-Flash block.
The CCIF flag is set when the operation has completed.

The Erase D-Flash Sector operation will erase all addresses in a sector of the D-Flash block.

Upon clearing CCIF to launch the Erase D-Flash Sector command, the Memory Controller will erase the
selected Flash sector and verify that it is erased. The CCIF flag will set after the Erase D-Flash Sector
operation has completed.
