26.4.2.14 Set Field Margin Level Command
The Set Field Margin Level command, valid in special modes only, causes the Memory Controller to set
the margin level specified for future read operations of a specific P-Flash or D-Flash block.
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
Freescale Semiconductor
1. As defined by the memory map for FTM512K3.

User margin levels can be used to check that Flash memory contents have
adequate margin for normal level read operations. If unexpected results are
encountered when checking Flash memory contents at user margin levels, a
potential loss of information has been detected.
