Running the Full Partition D-Flash command a second time will result in the previous partition values and
the entire D-Flash memory being erased. The data value written corresponds to the number of 256 byte
sectors allocated for either direct D-Flash access (DFPART) or buffer RAM EEE access (ERPART).

24.4.2.15 Erase Verify D-Flash Section Command
The Erase Verify D-Flash Section command will verify that a section of code in the D-Flash user partition
is erased. The Erase Verify D-Flash Section command defines the starting point of the data to be verified
and the number of words.

Upon clearing CCIF to launch the Erase Verify D-Flash Section command, the Memory Controller will
verify the selected section of D-Flash memory is erased. The CCIF flag will set after the Erase Verify D-
Flash Section operation has completed.

The D-Flash user partition will start at global address 0x10_0000. The buffer RAM EEE partition will end
at global address 0x13_FFFF. After the Full Partition D-Flash operation has completed, the CCIF flag will
set.
