Valid margin level settings for the Set Field Margin Level command are defined in
25.4.2.15 Full Partition D-Flash Command
The Full Partition D-Flash command allows the user to allocate sectors within the D-Flash block for
applications and a partition within the buffer RAM for EEPROM access. The D-Flash block consists of
128 sectors with 256 bytes per sector.

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.
