Upon clearing CCIF to launch the Set Field Margin Level command, the Memory Controller will set the
field margin level for the targeted block and then set the CCIF flag. Valid margin level settings for the Set
Field Margin Level command are defined in
18.4.2.14 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.

FSTAT
Field margin levels must only be used during verify of the initial factory
programming.
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.
