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 Program D-Flash operation programs one to four previously erased words in the D-Flash block. The
Program D-Flash operation will confirm that the targeted location(s) were successfully programmed upon
completion.

A Flash word must be in the erased state before being programmed.
Cumulative programming of bits within a Flash word is not allowed.
