20.4.2.14 Erase Verify D-Flash Section Command
The Erase Verify D-Flash Section command will verify that a section of code in the D-Flash 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.
20.4.2.15 Program D-Flash Command
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.

FSTAT
Field margin levels can be used to check that Flash memory contents have
adequate margin for data retention at the normal level setting. If unexpected
results are encountered when checking Flash memory contents at field
margin levels, the Flash memory contents should be erased and
reprogrammed.
